New problem updating to iTunes 11.1.4

I did all that...still have same missing .dll error message.

😟

What OS sre you running?

What is the exact error message?

tt2

Actually 2 error messages: "The program can't start because MSVCR90.dll is missing from your computer."

"ITunes was not installed correctly. Please reinstall ITunes. Error 7 (Windows Error 1 26 ).

I am using Windows Vista Home Premium.

Thanks.

The second error is expected after the first and can be ignored. The first one is the problem. Wiping out the entire iTunes installation, including the listed folders, and then reinstalling really ought to fix it.

I've just searched my Apple/iTunes folders and don't see a copy of the file which would imply it is installed somewhere else. I've also searched the iTunes installation log to see if I can find exactly which version of the dll is installed and where, but no luck. It does seem that Vista might be implicated in the repair failure, but I'm not quite sure yet. It might be "self-healing" some of the changes that iTunes tries to make.

I'll hunt around for more information.

Doh! You made a typo with MSVCR90.dll and I didn't catch it when I copied the text to use as a search term, which explains my failure to find anything useful. The relevant part of the install log is this:

WriteRegistryValues: Key: \Software\Microsoft\Windows\CurrentVersion\SideBySide\PatchedComponents, Name: {44272B9A-54E0-D091-B01F-C8B3B9A1E18E}, Value: C:\WINDOWS\winsxs\x86_Microsoft.VC80.CRT_1fc8b3b9a1e18e3b_8.0.50727.6195_x-ww_4 4262b86\\msvcr80.dll

Would you please select the text below and copy with CTRL+C

C:\WINDOWS\winsxs\x86_Microsoft.VC80.CRT_1fc8b3b9a1e18e3b_8.0.50727.6195_x-ww_44 262b86

then press Windows Logo Key + R, then press CTRL+V to paste, and then click OK or press return.

You should either get a folder not found error, or the folder should open. If the folder opens you should see the following files.

Either they are not there, or there is a permissions issue with them, or with the registry key that lets iTunes know where to find them.

Please let me know what happens.

tt2

Or another possibility is that the folder name isn't meant to be consistent across installs. 😟

I've just checked for the same folder on a 32-bit Windows 7 box and it is not found. I was looking from Windows XP earlier. I'll try and work out what the alternative addresses might be. I'm also assuming that you have 32-bit Vista, but would you please confirm? Thanks.

tt2

OK, I seem to have found the relevant folder on Windows 7, although the way the library is installed seems much more complicated, not that I understand the log anyway. I don't yet know if Vista should look more like XP or 7, but I suspect the latter.

The path I have is:

C:\Windows\winsxs\x86_microsoft.vc80.crt_1fc8b3b9a1e18e3b_8.0.50727.6195_none_d0 9154e044272b9a

and here is what is in it:

I spent the afternoon with McAfee to get the download. I tried several times and got the missing dll file error. The guy told me that it is an issue that everyone is having. He had me uninstall ITunes, ITunes Update file, Mobile Device Support file, Bonjour and Apple App Support file. He said they had to be uninstalled in that order. Once they were all uninstalled, I went to the Apple website and downloaded the latest version on ITunes. Now, all is well.

I followed all of the steps to delete and reinstall iTunes and I am still getting the message to reinstall...is that because I am still running on Windows 7? Is anyone else having issues with Windows 7 and iTunes?? I read but I don't understand your post that mentiones Windows 7...could you please help me?!

Did you try the steps in the two boxes in the user tip Troubleshooting issues with iTunes for Windows updates?

If not it would be worth trying again or we can try something more targeted.

If you'd like me to see if there is something more specific I can suggest please copy down the exact error messages that you get when you try to start iTunes.

In addition could you please go into Control Panel > Programs and Features and tell me which of these items are shown as installed:

Apple Application Support

Apple Mobile Device Support

Apple Software Update

Bonjour

iCloud

iTunes

HI,

I can't find either the QTMovieWin or QTMovieWin.dll files to delete them. I followed the directions you gave me, however, I could not find Apple Application Support, Apple Mobile Device Support, Apple Software Update or Bonjour. Some of them where there the first time I removed iTunes. The error I am currently getting is: "Apple Application Support was not found. Apple Application Support is required to run iTines. Please uninstall iTunes, then install iTunes again. Error 2" Is there a way I could just download Apple Application Support? Would that even help?

See Standalone Apple Application Support. If you can install that then you may be able to run the iTunes installer successfully.

Hey tt2. I retried "Removing and reinstalling iTunes and other software components" and it finally worked. My i Tunes is up and running. Thank you sir! 🙂

You're welcome. 🙂
