There are many reasons why installation errors may occur, so we will try to consider all options and invite you to familiarize yourself with detailed instructions to eliminate errors.

Getting rid of problems with the wrong version

It is also possible that the program version is incompatible with your operating system. For example, any version is suitable for Windows 7, Windows 8 and Windows 10. Regarding operating rooms Windows systems XP and Windows Vista, That latest version for them is 12.1.3.

There is also a special iTunes version 12.1.3 for 64-bit Windows versions Vista – you can download all these distributions on the official Apple website. It's best to take advantage automatic form, which will determine the version of the OS you are using and itself will offer a suitable distribution.

Clean your computer from accumulated garbage using special utilities;
Perform Cleanup system registry With using CCleaner(or using any other well-known utility);
Install all latest Windows updates.

If you don't have iTunes installed, click on the distribution right click and run the installation with administrator rights - as a rule, this procedure helps in many cases. If this is necessary, the system will require you to enter the administrator password - this happens if a password is set for the administrator account.

Good day to all Internet users! Today's article will answer the question why iTunes is not installed on Windows 7, 8 and XP. As you understand, The operating system version usually does not affect this problem and therefore the information below should help you.

The problem is really relevant, since every day there are more and more users who prefer the iPhone, and, as you know, with using iTunes users this phone upload and download files to your computer or laptop. Thus, if this software from Apple is not installed, then users will not be able to download data to their computer or laptop.

Let's look at the main ones possible problems that may interfere with this procedure:

Firewall

Go to “Start” - “Control Panel”, on the left in “View” select “ Small icons" And last step, go to "Windows Firewall".

On the left side of the window we see the inscription “Enable and disable Windows Firewall" We go there and turn it off, since this creation from Microsoft built into the system can interfere with iTunes.

Removing program remnants

If you incorrectly remove a program (if it has already been installed) that you want to install, it may cause an installation conflict. To do this you need to remove unnecessary files programs, and also clean the registry.

To begin, make sure that you at the moment you don't have it installed iTunes programs. Go to “Control Panel” - “Programs and Features”. Now go through the entire list carefully to be sure lack of iTunes. If you find it on this list, then delete it; if not, then read the article further.

Now open drive C. Next “Users” (maybe “Users”), then open your personal folder, then “AppData” - “Local”. We look for the “Temp” folder here and delete it. If it doesn’t work, go there and clean some of the files until everything possible is deleted. To delete all files you must reboot and then try to delete all files in this folder.

IN AppData folder also check availability iTunes folders. If it is there, then remove it and restart your computer.

Also clean the registry of unnecessary branches. To do this, download CCleaner program. If you haven’t used it, here’s a link to an article where I told you how to clear parameters in the registry: “”.

Hosts file and DNS reset

Another reason when iTunes is not installed is “wrong” hosts file. Go to C:\WINDOWS\SYSTEM32\DRIVERS\ETC - get to the hosts file. Right-click on it, select "Open", then click on "Notepad".

Now delete only this file and restart your computer. Next, do the following: go to “Start” - “Run” - type cmd and press Enter. A window will open, enter ipconfig /flushdns and press Enter. Next, try installing iTunes.

Greetings, blog readers.

For one reason or another, many users have to use a special program from Apple - iTunes. This question is especially relevant for owners of music iPods And iPhone smartphones. The fact is that this particular application allows you to transfer files to the device and back. Of course, there are other solutions, but they end up using the drivers from the program listed above. But due to the fact that the solution is hosted on a competing operating system, iTunes often gives an error when installing. This may be due to different problems. In the following article, I will try to analyze the main points due to which users are unable to install the desired application on the system.

During the installation of the program we need on the computer, a message often appears: “ Windows Installer package error" In addition, the text states that the application you need to complete cannot be launched, and it is best to contact technical staff for assistance.

Of course, if you don’t know the exact solution, you won’t be able to fix the problem that easily. Fortunately, there is a way out:

This should help with the problem.

MS VC++()

Sometimes the illness is associated with the work of a component such as Visual C++. This is usually accompanied by a message that mentions " Microsoft.vc80.crt».
Don't get upset right away. Download from official page update Microsoft Visual C++ 2005 SP1 and install it. Next, we go here and post the update. This should solve the situation. If not, you should contact official support Microsoft.

Installer()

Sometimes problems are related to the service. As a result, not only iTunes, but also any applications are not installed.

To solve the situation, we perform several movements:

Everything should work.

The service is restarted here Apple Mobile Device if there are any problems with it. A similar problem occurs not only when installing an assembly component, but also when normal startup programs.

()

Sometimes, when users install a new application on their device, a message may appear saying " the program is not a win32 application».

It’s worth saying right away that the problem is not related to the system’s capacity.

This often occurs when a project is intended for a completely different operating system. Or it simply has the wrong configuration.

The solution consists of several stages:

Miscellaneous errors()

In general, when installing iTunes on a computer with Windows 10 or any other version, you may see various problems. They all have the same cause. But depending on other components, appear various codes. So, for example, it could be 2503 and 2502. In addition, an ailment with code 2932 is often encountered. In some cases, the type of problem has a different appearance. So, for example, a window appears in front of users saying that the procedure cannot be continued due to Windows Error 127.

In general, everything can appear as a result of various problems:

Corruption of iTunes-related registry entries.

Malicious action software(This is especially often accompanied by error 2503).

Another program independently deleted the necessary files.

To prevent future problems, it is important to eliminate all possible factors:

Clearing the registry from unnecessary entries. This can be done using different programs, which I have mentioned more than once before.

Scan your system for viruses.

Update your drivers. I also talked about this before. This point is especially relevant if a warning message with a code appears 0xc000007b.

Install Windows updates.

If none of the above helps, perhaps only clean hosting of the operating system will work to solve the problem of building Microsoft vc80 and many others.

Rare cases()

Sometimes users may encounter a message that says it is missing.

You can easily fix this - just download and install the update for the universal C environment. You can download it here. This should also help if a window appears with the message: “ Cannot register module».

It is worth noting that it is better to perform all actions as an administrator.

In some cases, there may be an illness and a sign that says the following: “ Your system has not been modified" This often happens when users have previously installed a program and uninstalled it, leaving some traces.

The solution is simple:

What does this procedure mean? Thus, you said goodbye to all possible mentions of the application. After this, it is best to further clean the system using a special program.

As always, you can watch a useful video on the topic:

I hope this article will help you cope with the problem. Subscribe and tell others.

So, you bought a brand new iOS device and now you need to install the iTunes program on your computer, without which you won’t even be able to simply transfer music to your Apple. You download the program, run the installation and... the system gives an error!

What to do and what to do in such a situation? In this article we will tell you why the iTunes installation may not start and how to solve the problem.

The first reason why iTunes may refuse to install is, of course, trivial system failure. This type of failure can be easily resolved by restarting the computer. So yes, the first measure to eliminate problems with installing iTunes will be similar to measures to combat any other system bugs - just perform a reset!

Adjusting system settings

Another simple guide that can solve installation problems is adjusting the system time. Many may be surprised by this recommendation, but the fact remains that it is often incorrect set date/time on the PC causes serious bugs, including the refusal of iTunes to install.

Administrator rights

Reboot and adjustment system parameters didn't give the desired results? Then let's move on. Another popular reason why a particular utility is not installed on a PC is that the user is working through a guest account - to fix the problem, you will need to log into the system using an account with administrator rights.

If you do not practice account separation, then try the following - right-click on the iTunes installation file and select “Run as administrator” from the drop-down menu.

Blocking by security programs

iTunes installation still won't start? This means it’s time to start adjusting the settings of security utilities. The fact is that sometimes antivirus software and/or firewall work too responsibly, introducing suspicious programs and those you trust 100%, particularly iTunes. To ensure that security services do not interfere with the installation, we recommend turning them off completely while the procedure is being carried out.

Of course, you can not disable the utilities, but simply make adjustments to the settings by adding iTunes to the list of trusted programs, but sometimes this measure is not enough.

"Tails" of previous versions of iTunes

If iTunes does not want to install even with security programs disabled, it may be due to other software conflicts. In the event that you have already installed iTunes on your PC and then incorrectly removed the program, interfere new installation maybe, let's say, the “tails” of the previous version.

To check whether the previous one has been completely removed, download some unstyler, for example, Revo UnInstaller, install the program, run it and through the search find the following “tails” - iTunes, Quick Time, Bonjour, Apple Software Update, Apple Mobile Device Support and Apple Application Support. Delete everything you find from this list, and then don’t forget to reset your computer.

Update

Continuing the topic of software conflicts, it is important to say that these can be caused by utilities that have not been updated for a long time. Therefore, if after cleaning the “tails” the iTunes installer still refuses to work on your computer, it’s time to visit “Windows Update” (“Start”, “Update Center ...”) and see if there are current undownloaded updates - if any , complete them all. Then be sure to restart your computer and try running the iTunes installer again.

Version detection error

Is the installation still failing with an error? Well, the reasons and solutions to the problem are not over yet. The next one is this. Sometimes Apple program does not identify correctly Windows version, you should especially pay attention to this reason if iTunes is not installed on Windows 10.

How do you usually download iTunes to your computer? The user must go to the official Apple website in a special section and start downloading; at the time of downloading, the version of the platform installed on your computer will be determined and the corresponding version of the program will be downloaded. If the version is not detected correctly, iTunes installation will fail.

If you suspect that you are encountering this particular problem, try manually selecting the version you need on this page of the Apple website and installing it.

Windows Installer Errors

And finally, the last of the most probable causes iTunes installation errors are problems with the Windows Installer service. Perhaps for one reason or another this service was accidentally disabled and to correct the situation you will need to activate it. To do this:

We hope that after this procedure iTunes will be installed on your PC.

Viruses

We started the article with banal advice - reboot, and we'll end with banal advice - check your computer for viruses. What can you do, no one has canceled malware, and if it is running on your computer, then not installing iTunes is far from the biggest problem that threatens you. So be sure to check your PC for viruses, first making sure that you have a good and updated antivirus.

If nothing helps?

We believe that by doing one of the steps above, you will most likely get the iTunes installer to work. If these guides do not solve the problem, we recommend contacting our service. Apple support- The company’s specialists will definitely help.

In many articles devoted to the problem “iTunes will not install on Windows 10, 7, XP, etc.”, you can find advice to delete or fix the hosts file, as well as perform a number of other actions that are difficult for the average user to understand. As a result, an attempt to solve the problem may result in further big problems. That is why we recommend contacting the support service, in this case, even if you have to perform some complex actions, you will work under the strict guidance of understanding people and everything will end successfully!

Ctrl+Enter.

In most cases, iTunes is installed on your computer without problems, but sometimes errors still occur. You may see such “scary” phrases as - “The installer encountered errors before the iTunes configuration”, “An error occurred while installing an assembly component ", "Happened unknown error" - and these are just the most known bugs installations.

However, no matter what error you encounter, you should not be afraid, even if you do not understand at all what this error is. Just follow the recommendations in this article and you will be able to fix everything.

Let's start with the simplest recommendation - restarting the computer. Despite the banality of this advice, it often turns out to be effective, and when dealing not only with iTunes errors of various types, but also with any other software glitch. So we confidently press reset with the hope that we will be lucky and the problem will be solved in such an elegant and simple way.

Login to an account with administrator rights

Reboot didn't help? Well, then we begin to study the problem in more detail. The first thing you have to do is check what rights the account under which you work on the computer has.

Typically, the right to install programs is granted only to an account with administrator rights, so if you are working in a guest account, you should not be surprised that iTunes refuses to install; any other program from the guest account will not install either.

By the way, this reason for iTunes installation error is popular when the user tries to install the program on a work computer without having administrator rights. If the computer is at home, then most likely you are working as an administrator. And, nevertheless, we recommend that you make sure of this:

On work computers, there is often an option to assign your own account administrator rights, not available. In this case, try the following - right-click the iTunes installation file and select “Run as administrator” in the window that appears.

If failure awaits you here too, contact system administrator or your superiors and ask them to grant you rights to install the program. Just be prepared to explain to your boss why you need iTunes during work hours.

Updating software on your computer

If everything is in order with your rights, and iTunes refuses to install, the problem may be software conflicts, which are most often a consequence of the presence on the PC updated programs. So the next step to fix the error is to download current updates. If you have a Mac, go to the App Store, tap “Updates” and download all the latest ones. If you have Windows, call the “Start” menu, then “Windows Update”, run the scan, and then download the updates found.

Checking PC Compatibility with iTunes Version

Another possible cause of a software conflict is inappropriate version iTunes. If you drive in any popular search engine the phrase “Download iTunes”, then the first link will take you to the official Apple website, to the page where the most current version of this program is located. However, if you have Windows XP or Windows Vista, and even a 32-bit system, the most current version will not suit you. For users of the above versions of Windows, Apple has created special versions of iTunes, you can download them.

We emphasize that the minimum system requirements for myself current version iTunes - 64-bit system, Windows platform 7 and above.

Disabling security programs

List software conflicts not yet finished - another one - prohibiting the installation of iTunes by security utilities. If you have antivirus programs installed or a firewall turned on, they may be doing their job too hard, blocking malware or not. iTunes may be blacklisted for one reason or another. To check if this is the case, the easiest way is to disable security utilities while installing the program.

However, if you are afraid to disable protective services completely, delve into their settings and move iTunes to the list of trusted programs.

Cleaning the tails of past iTunes installations

And finally, last reason software conflicts - components of past iTunes installations. If you have previously installed iTunes on a computer that you are currently experiencing problems with, then most likely you simply uninstalled the previous version incorrectly. In that case best option- download an uninstaller, for example, Revo UnInstaller and find it in it following components- Apple Application Support, Apple Mobile Device Support, Apple Software Update, Bonjour, QuickTime - all these are the “tails” of iTunes; if any of the components is detected, we remove it using the program.

After Apple removal Software Update, this component will need to be reinstalled. In general, in theory, when installing iTunes, this element should be installed automatically as a component of the program, but after removing it manually, problems often arise, so it’s still better to install it yourself:

Ready! Now you can try to install iTunes, but you need to start the installation, again, not using the iTunes.exe file, but through iTunes.msi, which is located in the .zip “folder”.

Activating Windows Services

And finally - another reason, separate from software conflicts, why iTunes, which persistently gives an error, does not want to be installed - this is a problem with Windows services - “Windows Installer” and “Installer”. Windows modules" Typically, the problem is that one of these services is disabled for one reason or another. To resolve the service error, you must enable:

Let's summarize

Well, now you know why an error of one kind or another may occur when installing iTunes, and how to fix it. We hope the methods indicated in the article helped you. If the program flatly refuses to install, we recommend contacting Apple support.

If you find an error, please highlight a piece of text and click Ctrl+Enter.

There may be an answer here: https://support.apple.com/ru-ru/HT201668

iTunes isn't installed on your computer and you can't get started with your Apple gadgets? Don't despair - we will help you solve this problem. There are many reasons why installation errors may occur, so we will try to consider all the options and offer you to read how to troubleshoot errors.

First you need to figure out where you got the program distribution from. If a friend gave it to you or you downloaded it from some “left” resource, delete it and go to the official Apple website, where you can download a known good and working distribution. It is also possible that the program version is incompatible with your operating system. For example, any version is suitable for Windows 7, Windows 8 and Windows 10.

As for the Windows XP and Windows Vista operating systems, the latest version for them is 12.1.3. There is also special version iTunes 12.1.3 for the 64-bit version of Windows Vista - you can download all these distributions on the official Apple website. It is best to use the automatic form, which will determine the version of the OS you are using and will automatically suggest a suitable distribution.

Next, it’s a matter of technique – download the distribution and try to install it. If your computer is running Windows Vista, be sure to run the installer as an administrator. We can also advise changing the Vista “curve” to Windows 7 or a more modern Windows 10.

You can't install iTunes and you just can't find the reason for what's happening? Then we recommend that you follow these steps:

Clean your computer from accumulated garbage using special utilities;
Clean the system registry using CCleaner (or any other well-known utility);
Install all latest updates Windows.

After this, reboot and restart the installation procedure.

What other problems may await a user who does not have iTunes installed? If the installer complains about the Windows Installer service, you need to start the service through “Control Panel - Administrative Tools - Services”. You may also need to update the Windows Installer service - the corresponding package is downloaded from the official Microsoft website. Install the package, reboot and re-install.

The next problem may be insufficient rights for installation. If you do not have iTunes installed, right-click on the distribution and run the installation with administrator rights - as a rule, this procedure helps in many cases. If this is necessary, the system will require you to enter the administrator password - this happens if a password is set for the administrator account.

What to do if all the updates are installed, the garbage is removed, the Windows Installer service is running, the installation is launched under administrator rights, but the installation still does not start? Why can't iTunes install on my computer? The problem may lie in an application conflict - try temporarily disabling firewalls and anti-virus programs that block any ports, drives and the ability to install software normally.

If your operating system is literally teeming with errors, slows down and loads slowly, do not be puzzled by questions and actions, but simply reinstall Windows.
