It seems as though some users have issue installing or updating iTunes. Here we list the common iTunes installation errors and also the corresponding workarounds.

Windows Installer package error

You may receive one of the following error messages when updating or installing iTunes for Windows:

"There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor."

"There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor."

This iTunes install error is not strange to some users who came across the same iTunes 12.6/12.5/12.3 installation error on Windows 10. The most common cause of the errors is outdated or incompatible version of Apple Software Update on the PC. To fix this issue, follow these steps.

iTunes Error 7 (Windows error 193) when you try to install iTunes for Windows

"I am running W7 64-bit. Every time I try to install ITune I get an Error 7 (Windows error 193) upon completion ( and another pop up that says 'iTunes helper was not installed'). During the installation process I get a message that Apple Mobile Device Service was unable to start. To which I select 'Ignore'"

This is another error message that occurs during iTunes installation. You can follow the steps to resolve this error.

Note: The steps below are only applicable when the message contains error 193, but not other Windows error code.

1. Head to C:\Windows\System32

2. Locate the following files and remove them to Recycle Bin.

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

Make sure that the file names that you drag to the recycle bin match those above exactly. If you cannot locate a file, skip and go to the next file. Any other files should not be removed from this folder.

3. After you drag these files to Recycle Bin, go and perform a repair on both installed versions of Apple Application Support (64 and 32-bit) in the Add/Remove Programs list in the Control Panel. iTunes requires both 64 and 32-bit versions of Apple Application Support.

4. Launch iTunes. If iTunes won't launch and you see the error 7 (Windows error 193) again, you should reinstall iTunes again.
