Error 7 (Windows error 126)

This worked for me. Thanks for the post.

I did the suggeston below and uninstalled all of my Apple products. With the reinstall it works just fine. However it did not reinstall, Quicktime.

Did you uninstall Bonjour too?

Yes, Bonjour was one of the first 6 Apple programs that was specifically mentioned as needing to be uninstalled. If your iTunes reinstall is working then I guess you didn't need to remove Bonjour after all. Quicktime was not reinstalled on my Pc when I reinstalled iTunes. Only the first five programs in the list above are reinstalled with iTunes. You will have to reinstall the reast or let Apple Software Update do it if it prompts you to add them.

I tried the steps listed....all is working properly.

Thank you!!!!

THIS WORKED!! Thank you SO MUCH. I tried everything else, but you had the key--uninstall everything Apple, restart your computer, then RE-install iTunes. It came right up! Thank you!

AMEN!!! I now have iTunes back and it works! I have jumped through hoops for the past 24 hours trying to get iTunes to install and get rid of all the error messages and the note about msvcr80.dll. I went so far as to search my computer for all the files that were said not to exist and they all existed! AND to find it was as easy as deleting all things Apple and then re-installing. Wish I had found this forum last night--for some reason it didn't show up in any of my searches.

Obviously Apple has had this problem before and they should know better.

I have had the same problem - how did you resolve it.

I dont know how to do this without fiddling and messing my computer, anyone have the patience to guide me how to do this plus the MSCVR80.dll that is also missing an dit wont recognise a new Iphone says DO I HAVE PERMISSION

I deleted everything Apple. Just went down the list in the uninstall window and uninstalled it all. I did this in the order mentioned in someone else's post: iTunes, Apple Support, Apple Mobile Device, Bonjour, Apple Application Support, iCloud, Quicktime, VoiceOver Kit, and anything else on your computer created by Apple. Then I restarted my computer and downloaded iTunes. (The Apple products in my list have shortened names because that is what I wrote in my notes) The list I followed was posted by lel1956. Hope you get good results.

The files are most likely NOT missing. Do not know what is causing this but just uninstall everything Apple as I said in my reply to DavidPugh, then turn your device off, turn it back on and install iTunes. I'll bet it works! It has for others on this forum.

I had the same problem and fixed it by uninstalling and reinstalling all my apple apps on my Windows PC.

Thank you for the advice. It has worked.

I did this and it also worked. I still do not know what caused the problem in the first place. Is there a bug in the latest itunes release ?

Which "this" did you do?

What was "it"? Which response did you use to get iTunes installed?
