iTunes install errors: MSVCR80.dll and Error 7 (windows error 126)

All of a sudden my iTunes stopped working, and I get the following error messages:

1. the program can't start because MSVCR80.dll is missing from your computer. Try reinstalling the program to fix this problem

and

2. iTunes was not installed correctly. Please reinstall iTunes. Error 7 (Windows error 126).

Now I've checked the forums and followed the advice of uninstalling all Apple applications, rebooting, and reinstalling iTunes.

This is not working. I've tried installing as Administrator but doesn't make any difference at all.

There must be a way to fix this? I'm not a tech geek but I want to avoid having to take my laptop back to factory settings to sort this out.

Thanks

Apple reworked the installer slightly on Feb 6th. Seems to update more reliably for some but for others the issues remain. Those that still have difficulties should see Troubleshooting issues with iTunes for Windows updates.

G'day kevin120,

What is the status of the Mr. Fix-It ?

Also can you be more specific as to which Mr. Fix-It you are using.

- most of these type of utility programs remove redundat registry entries, however I have not had one that fixes installation errors to make a application program work !

When You said,

"If I try to reinstall by going to the iTunes website, it goes through most of the motions only to tell me at the end that the "iTunes Installer Interrupted. Errors occured during installation before the requested operations for iTunes could be completed.""

simply tells me that the procedures in the 3 steps have not been completed correctly !!

As for the "Windows Install Clean Up" don't believe everything you read as I have been using it on ALL Win OS's from XP up to 7. So far I have not needed to use it on Win8 but I will install it to see if it will work and let you know for the benifit of forum members.
