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

G'day ilkaflood,

Technically challenged ?, rubbish I say.

You can use a Computer and I think you can also follow clear printed instructions because Apple will not bring out a fix, as they already have !!

How about going to the respective hyperlink for your operating system.

This is the post and I recommend that you expand the OS applicable to your System.

Its a pain in the rear having to do all this, but it works ☺

HT1925: Removing and Reinstalling iTunes for Windows XP

HT1923: Removing and reinstalling iTunes for Windows Vista, Windows 7, or Windows 8

When you have loaded the respective link, remember to "Expand all " option at the top just above the bold black "Overview", print a hard copy of the instructions and when you follow each Stem 1, 2 and 3 and tick off the task as you have completed each item, also remember to reboot after each step, i.e. after Step 1, then 2, then 3, before you start using iTunes again !.

I have folowed them on at least 37 different windows operating systems and they work !!

I suppose you could call me a 72 year old Technically Un-challenged Grandad and if I can do it, so can you.😀

I was going to offer and do this for you, alas the Admin of this Forum will not allow me to give you my TeamViewer number or Skype ID so we could communicate.

jeetu6600,

I have no idea why you are making all these posts in reply to the original "penelope184" post ?

Obviously you don't or have not taken any notice of what penelope184 has posted on the original.

She has fixed the problems a long time ago !! 😉

Thank you. Uninstalling all Apple and Itunes and then reinstalling Itunes worked.

Thank you so much. I experienced the same problem with the msvcr80.dll error, and could not open Itunes. The steps you provided to uninstall and re-install Itunes worked. My library and data was restored successfully.🙂
