In our previous instructions for novice iPhone and iPad users, we succeeded, after which we looked in detail, found out that this program is distributed free of charge, but forgot about one very important point– bit depth operating system PC, which affects compatibility with .

Some users were unable to install iTunes and asked in emails - Why won't iTunes install? Other users had iTunes installed on their computer, but for some reason it wouldn’t launch. One of the reasons for such problems may be that the version of iTunes does not match the bitness of the computer's operating system.

Users of the Mac OS X operating system may not read further, but Windows owners should know that operating systems Windows systems There are 64-bit and 32-bit (64 bit and 32 bit). Therefore, you need to download iTunes corresponding to the bitness of the PC OS. In the first part of the material, I propose to learn how to determine the bit depth of your computer operating system and find out whether it is 32-bit or 64-bit. And in the second part we will learn how to choose the right iTunes for the operating system.

Windows 7 bit depth
Today, many people use Windows 7 on their computers; to determine the bit depth, we do the following:

1. Click the “Start” button in the lower left corner and enter the word in the search column - System. You will see this very System in the search results above, click on it. If that doesn't work, you can alternatively right-click on the My Computer icon and select Properties.

2. As a result, a window should appear for viewing basic information about the computer, where in the System section you can look at the System type and see Windows bit depth 7. In the example above we see a 64-bit operating system. If you have a 32-bit one, then instead of the number 64 the computer will display 32.

Windows XP bit depth
With XP everything is pretty much the same, but there are some peculiarities.

You can, as in the case of 7, right-click on the My Computer icon and select System Information Properties in the General tab. If there are no bit numbers there, but simply says Windows XP, this means that the system is 32-bit. In 64-bit versions of XP there is a number - 64.

1. Additionally, you can verify the bitness of XP as follows: Start – All Programs – Accessories – System Tools – System Information.

There is another, shorter way: Start – Run – enter in English letters winmsd.exe and click OK.

2. A window with information about the system opens, look at the Processor column; if it starts with X86, the operating system is 32-bit. In the case of a 64-bit version of the OS, the Processor section will start with the inscription IA-64, or other abbreviations containing the number 64.

It seems that we have sorted out the bit depth of operating systems, now you need to download the appropriate iTunes for your OS. By default, the 32-bit version is available for download on the iTunes download page on Apple's website, as it is more common among users. To download 64-bit iTunes, you can go to search engine Google and using the query - iTunes 64, find the 64-bit version.

Installation iTunes file for 32-bit systems it looks like this - iTunesSetup.exe
The iTunes installation file for 64-bit systems looks like this: iTunes64Setup.exe

We hope that now you will be able to install iTunes for any operating system. Users of the Mac OS X operating system, install iTunes for Mac, as far as I know you have no problems with bit depth.

Many users have fallen in love with the iTunes application, which is used on gadgets like iPod, iPhone, iPad, as well as on PCs. For normal operation in any program, system requirements and compatibility with the OS are first indicated. In this article we will focus on Windows 7 and later versions that are often used nowadays. Let's look at the main errors, why iTunes won't install or start, and how to fix them.

iTunes does not install on Windows 7, 10 and other versions: let’s look at the main problems

Let's start with the fact that each program has its own requirements for installing. Therefore, first of all, let’s take a look at the requirements for installing iTunes.

System requirements for Windows

Hardware:

• PC with Intel or AMD processor supporting SSE2 (1 GHz) and 512 MB RAM
• To view videos in standard format from the iTunes Store, you need Intel processor Pentium D or faster, 512 MB RAM and a DirectX 9.0 compatible video card.
• Requires a processor to view 720p HD video, iTunes LP content, and iTunes Extras Intel Core 2 Duo 2.0 GHz or faster, 1 GB RAM and GPU Intel GMA X3000, ATI Radeon X1300 or NVIDIA GeForce 6150 or more powerful.
• To watch 1080p HD video, you need an Intel Core 2 Duo 2.4 GHz or faster processor, 2 GB RAM and an Intel GMA X4500HD, ATI Radeon HD 2400 graphics processor, Nvidia GeForce 8300 GS or higher.
• Viewing iTunes LP and iTunes Extras requires a screen resolution of 1024x768 or higher; 1280x800 or higher
• 16-bit sound card and speakers
• Broadband Internet connection required to connect to Apple Music, iTunes Store and iTunes Extras

• 400 MB free disk space
• Screen reader requires Window-Eyes 7.2 or later; For iTunes availability, see www.apple.com/ru/accessibility
• iTunes is now a 64-bit application for 64-bit versions of Windows. Some third party visualizers may not be compatible with this version of iTunes. Contact the developer to get an updated version of the visualizer that is compatible with iTunes 12.1 and later.
• Availability of Apple Music, Apple Music Radio, iTunes in the Cloud and iTunes Match may vary by country

Except system requirements, the correct installation sequence is also taken into account. We watch this process in the next video.

Video: how to install iTunes

Installation fails, or after installation I receive "error 2" or "Apple Application Support not found" messages.

In this case, perform the following steps.

• Check that you have computer administrator rights in the account you are logging in under.
• Try installing Windows updates and latest version iTunes for PC.
• Find the iTunesSetup or iTunes6464Setup folder and, by right-clicking, click “Run as administrator” in the context menu (for the XP version, “Open”). If the application has already been installed on the PC, the system will simply offer a program fix. After that, restart your PC and try running the application again.
• If you previously had iTunes on your PC, but you couldn’t install or fix the program, then possible solution will be the removal of the remaining previous installation components. Then try to install the application again.
• Disabling a security program or even uninstalling it.
• Restart your PC.

When I try to install iTunes, I get "error 7 (error 193 on Windows)"

This problem should be considered separately, since the solution to this problem is different from the others. This means that the PC has outdated or incompatible software. At the same time, the following messages appear: “iTunes is not installed correctly. Reinstall iTunes. Error 7 (Windows Error 193)", "iTunesHelper is not installed correctly. Reinstall iTunes. Error 7", "The Apple Mobile Device Service could not start. Make sure you have the required level of rights to run system services."

To fix the problem, go to the folder C:\Windows\System32. Find files from the list and drag them to the trash:

• msvcp100.dll
• msvcp120.dll
• msvcp140.dll
• msvcr100.dll
• msvcr120.dll
• vcruntime140.dll

If the file is not found, move on to the next one. You should not delete other files from this folder.

Then try restoring both installed versions of Apple Application Support (64-bit and 32-bit). In the Add or Remove Programs section of Control Panel, highlight the 32-bit file Apple versions Application Support. Right-click to open the context menu and select “Fix”. We perform the same steps for the 64-bit version of Apple Application Support. Let's try to launch iTunes.

Windows Installer package error when installing iTunes

Problems when installing an application also appear due to problems with the installer. Windows Installer. A message appears on the screen.

The program may be disabled, try running it in manual mode. You can do this as follows. In the “Start” menu, click “Run” and enter “services.msc” in the field. A window will open with a list in which we find “Windows Installer”.

Open the file. The installer window appears. Here we select the launch type “Manual” and click “Run”.

It is possible that the program starts, but an error is displayed. In this case, we try to update Windows Installer.

We can find other options for eliminating the installer error using the links http://ioska.ru/itunes/oshibka-windows-installer.html and https://habrahabr.ru/sandbox/33155/.

iTunes won't start: how to troubleshoot

Partial troubleshooting during startup is discussed above (error 2, error 7). Don't forget to check for updates for Windows and iTunes before attempting to fix errors.

Since iTunes is an Apple product, when launching the application, as well as during installation, a conflict with third-party software is possible. To exclude this option, we include the application in safe mode. To do this, when opening iTunes, hold down Shift and Ctrl on your keyboard. After this launch, the “iTunes is running in safe mode” window will appear. The visual modules you installed are temporarily disabled."

Then click the “Continue” button and, if the program started in this way and works without problems, do the following:

1. Check with the manufacturer installed plugin information about compatibility with the required version of iTunes, as well as information about the availability of updated versions of this plugin.
2. Close iTunes and try temporarily moving third-party add-ons to your desktop.

iTunes program plugins and scripts are located in the following folders: C:\Users\username\App Data\Roaming\Apple Computer\iTunes\iTunes Plug-ins\, C:\Program Files\iTunes\Plug-ins; in Windows XP: C:\Documents and Settings\username\Application Data\Apple Computer\iTunes\iTunes Plug-ins\, C:\Program Files\iTunes\Plug-ins.

Startup errors also occur when it is necessary to update the program drivers. To check this, turn off the Internet and launch the application. If iTunes works fine, update the drivers.

Errors are only generated when working in a specific account. In this case, you can create another media library and if there are no problems with it, restore the previous version of the media library.

If problems appear again, you need to check your saved files, as some of them may cause iTunes to freeze or turn off spontaneously. To find such a file, do the following:

If the problem persists, repeat the steps, avoiding adding the files that caused the problem.

Let's not forget about system problems. Possible ways their solutions:

1. Check for potentially dangerous programs. Make sure your security software is up to date and run a system scan.
2. Try changing your security software settings.
3. Make sure correct installation iTunes. If necessary, reinstall the program.
4. Update your PC drivers.

Problems during update: what to do

The problems that arise during the iTunes update process are the same as when installing the application and we proceed in the same way as described above. However, there are individual cases that require the removal of Apple components installed on a PC. Watch the video to see how to do this.

Some issues have been sorted out. Of course, that's not all possible problems when using iTunes. Therefore, “for dessert” I’ll leave a couple of useful links! http://appstudio.org/errors - reference book iTunes errors, https://support.apple.com/ru-ru/HT203174 - error codes on the official website, and for those who want to expand the capabilities of the application - read about life hacks https://lifehacker.ru/2015/05/15/10-tips -for-itunes/, https://www.6264.com.ua/list/13497.

Today the sphere mobile technologies continues to develop at a fairly rapid pace. Progress in production cell phones and smartphones becomes especially noticeable if you pay attention to how quickly Yesterday's new products become obsolete, unable to withstand the competition of newly released flagships. We will talk about eliminating one of the signs of such obsolescence below.

iPhone and iOS obsolescence

In one of our previous articles: - we looked at an option that allows you to play online videos in high quality on an old computer.
But if the process of obsolescence of hardware in most cases can be considered natural and necessary, then with software everything is not always so obvious.

In the issue of software obsolescence, two main directions can be distinguished:

1. Lack of support and release of operating system updates by the manufacturer for old devices
2. Lack of backward compatibility of new versions software with old OS

Support period

The first point is clear. The smartphone manufacturer does not want to spend effort and money on optimization of the new system for outdated hardware, even if this task is technically feasible. In addition to saving resources, this step also contributes to the rapid growth of sales of new manufactured devices (in this case we neglect the outflow of the customer base to a more loyal manufacturer), which also does not speak in favor of increasing the duration of support for its products.

Software backwards compatibility

As for the question backward compatibility, then this side may seem even more controversial. To begin with, let us give a conditional answer in the context of the current article to the question: What is backward compatibility?

backward compatibility- is the ability of new software versions to work with old data formats on an old operating system

Both versions of this problem are very acute for owners of previous releases of the company’s cell phones. Apple.
For example, the latter is available to owners iPhone 4S version iOS - 9.3.5 , For iPhone 4 the situation is even worse; this device can only be officially installed iOS 7.1.2. And this despite the fact that latest version of Apple operating system at the current time - 10.3.1

Consequences of software obsolescence

What does this mean?
One of the main troubles they will face users of outdated Apple devices- that, often, it is impossible to install some programs from App Store on iOS below a certain release.
In particular, to install such popular program exchanging quick messages and calls via the Internet, like Viber, availability will be required from the Apple store installed version iOS no lower than 8.1. For applications such as Skype, network client In contact with or mobile app Instagram, maximum old version of the phone system that meets the installation conditions for the listed software - iOS 8.0.

From all of the above, we can conclude that officially we do not have the opportunity install Viber on iPhone 4 . The same applies to the other programs mentioned: Skype, vk client for iOS, Instagram and many others. Moreover, the same fate will soon befall newer models, so this issue may in the future affect an increasing number of users of Apple products.

However, there is a way to install the same Instagram on iPhone 4. Work this method will be with most programs.
The essence of this method is to pre-download the application from the App Store with reference to Apple ID and subsequent installation of the supported version of the program on the phone itself.

So, we will need:

1. Computer with Internet access.
2. Connecting to the Internet on iPhone.

Let's get started.

Installing VK App in Apple ID via iTunes

If we try install the VKontakte program on iPhone 4, then nothing will work for us, we will get an error This content (app) requires iOS 8.0 or later with a proposal to update the device to iOS 8.0

But if we go along the path Settings - General - Software Update, we will see that we have installed " newest"Software, namely iOS 7.1.2, which is the latest for iPhone 4

This means that we will have to look for workarounds.

Download the program to your computer from the official Apple website iTunes and install it.
Let's launch iTunes and log in using the account with which your iPhone was activated.

Now in the upper left corner click on the drop-down menu and select Edit menu...

In the list that appears, check the box next to Programs and click Finish.

Next, in the drop-down list, go to the Programs section we added.
In the central part of the screen, click on the App Store tab. In the upper right corner, in the search bar, enter the name of the program we are interested in, let it be VKontakte client for iPhone. Click the button under the application icon Download, enter the password for your Apple ID and click the Buy button ( The app is free, nothing to worry about)

The application is downloaded to our account, we no longer need a computer.

Installing VK App on iPhone 4 via the App Store

We connect the phone to the Internet via mobile network or via Wi-Fi. Let's launch App Store on the device and can immediately go to the tab Updates. Here we will have the same application that we downloaded from iTunes, that is, the client VK App. To the right of the program icon there will be a button in the form of a cloud with an arrow, which allows us to install the application from the Apple ID.
Click on the cloud

Now we will see a notification that To download the latest version of the program, an updated version of the operating system is required. But here we will be asked download the previous version of this application, which we will use by pressing the button Download

We are waiting for the last one to finish loading compatible version and we can run the installed program.
It is worth mentioning that this way it will not be possible install the latest version of the program on iPhone(the solution to the issue is possible if you have a Jailbreak), that is, you will probably not have access to the full functionality of the application added in new releases, but this is most often not required for comfortable use of the main features.

Today we talked about how to install the program on an iPhone with an outdated iOS system.

Long support and constant updates to you.

Every year after the presentation new iPhones, Apple is releasing a new mobile system iOS. For developers, for the stability of their applications in new system, you also have to make changes and release new updates to your products in the App Store. Over time, older versions of iOS cease to be supported by both Apple and application developers. And if you are the owner iPhone models and iPads that do not run on the latest versions of iOS, you will easily encounter problems installing some applications and games.

Each developer in the App Store sets minimum requirements for their application (device and operating system version), and if you want to install the application, and your iOS version is lower than the minimum, then you will see this message:

“This content (app) requires iOS 8 (any iOS version can be specified here) or later.”

What you need to download an application from the App Store for iOS devices that are not supported (iPhone and iPad with an older version of iOS)

If you receive such a warning, do not be upset, there is a way out! Unfortunately, you won’t be able to install the latest version of the application, but you can download the previous one, which is compatible with your iOS.

To do this you will need:

• a computer with macOS or Windows with Internet access;
• installed iTunes software no higher than 12.6.5;
• accounting Apple entry ID that is used on a device with iCloud enabled (you can enable it in iPhone settings or iPad).

IMPORTANT! With the release of iOS 11 and iTunes update up to version 12.7, Apple removed the App Store from the media combine and now applications can only be downloaded on an iOS device - iPhone, iPad, iPod touch. Therefore, you need to install the latest version of the program from the App Store - iTunes 12.6.5. Read the following article to learn how to remove iTunes. To check the version you have installed:

• for macOS- in the menu bar, click “iTunes” → “About iTunes”
• for Windows- Select Help → About iTunes

Step 1 Launch on your Mac or Windows computer iTunes program

Step 2 Sign in with your Apple ID

Step 3 Go to “Programs” → AppStore and find the application you need or use the search

Step 4 Click the Download button

Step 5 After this you won't need your computer anymore, now take your iPhone or iPad and open it on it app Store

Step 6 Go to the Updates tab and select Purchases

In iOS 11 and higher, you need to click on the icon of your account, it is located in the upper right corner in all sections except “Search”

Step 7 Select the application you just downloaded on your computer and click (cloud icon with a down arrow)

Step 8 You will see a message with minimum requirements. To install the latest compatible version, iOS will ask, "Do you want to download a previous version of this app?" Click Download. After this, the download and installation of the application will begin.

If for some reason your purchases are not displayed in the “Purchases” section on your iPhone/iPad, then use the search in the App Store. Find the apps you purchased from iTunes on your computer using your Apple ID and click the Download button

Unfortunately, not all applications can be installed this way. For example, if you have a gadget with iOS 7, and the minimum available version download is designed for iOS 10, then most likely you will not succeed. In this case, you need to use the following instructions.

After downloading the application on your computer, the file can be deleted from the iTunes Library; it is still the version that will not suit you.

It is possible that while still installing on your iPhone or iPad iOS version 10.3, you noticed that when you opened certain apps and games, you were prompted to update them to work with future versions of iOS.

You can, of course, continue to use them from iOS 10, but if you're planning on upgrading to iOS 11 (if you haven't already), it's time to see if you'll lose your apps after the transition.

There's no need to open each app in turn to detect the warning above, although in addition to it, iOS 10.3 may display a list of all affected apps that are currently installed.

So, before following the steps below, make sure you have enough storage space on your device to update your current apps. Open the App Store and click Updates and Purchased on iPhone or simply Purchased on iPad.

If you have disabled automatic download apps in Settings > iTunes & App Store on any of your devices, you'll need to follow the guide below on each device to make sure you haven't updated an app that's on your iPhone 7 but not your iPad Pro.

Important! Upgrading to 64-bit has been a requirement for developers for several years now, so ask yourself if you need an app that hasn't been updated in years since Apple started moving to a 64-bit OS.

1. Check the list of applications

Under Settings > General > About, if the arrow to the right of the Applications row is missing, none of your apps require immediate action (though this doesn't guarantee they won't have other issues in iOS 11). If there is an arrow, tap it.

2. Check for updates

Now you can see a list of applications that need attention. There are applications here that have available updates, and those who don’t have them.

In the list of those with updates available, tap the app name to go to its app store page. Here you will see an Update button. Download the update and check again to see if iOS supports app compatibility.

3. Search for new versions

If an app is no longer available or has any updates or fixes, check to see if an app update is available as a standalone app: Find the developer's name in the App Store and look for anything similar to your app.

4. Ask the developer

Otherwise, ask the developer directly through their website if they have plans to update or replace the application.

5. Don't lose hope

If the app has been delisted, hasn't been updated in years, or if the developer himself has said he doesn't plan to update it, you may need to find something to take its place.

The second option is that even if an app is currently showing up as problematic for iOS 11, there is every chance that an update could come out even after iOS 11 hits devices, within a few months.

6. Find a replacement

If there's really no hope for an update for your app, there's a good chance there's an alternative in the App Store that you can look into.

Try to find keywords, related to the application. If it is, for example, a calendar, just search for “calendar”, of which there are a huge number. Alternatives may not be identical appearance and features of your old application, but in most cases you will be able to find a worthy replacement.

Of course, this won't help you with games, so if you don't particularly need iOS 11, you can play your favorite game for now until you get bored, and then switch to the new OS. After all, how much time can you waste on a game that you've already beaten a hundred times? And if not, then maybe it’s not worth it?
