HT5654 message after update app. failed to start because MSVCR80.dll wasn't found

I had a message to upgrade my version of Itunes so I clicked on the button to do this. During the download it stopped, coming up with an error message stating "This app failed to start because MSVCR80.dll was not found reinstall may fix problem" then after clicking on ok I get another box with the message "Error 7 (windows error 126)".
I have tried uninstalling every apple application I have then reinstalling them and still get the same message. Can anyone help?

Updating iTunes with error message "this application has failed to start because MSVCR80.dll was not found"?

After updating iTunes, has anyone got the message "this application has failed to start because MSVCR80.dll was not found. Re-installing the application may fix this problem." message and "iTunes was not installed correctly. Please re-install iTunes. Error 7 (Windows error 126)"? I've tried everything from un-installing and re-installing iTunes to deleting the SC Info. Any help would be greatly appreciated

Click here and follow the instructions. You may need to completely remove and reinstall iTunes and all related components, or run the process multiple times; this won't normally affect its library, but that should be backed up anyway.

I've just (finally) managed to fix this problem today. I checked the Apple Support forums, and it seems a lot of people are having the same problem.
I rang the Apple Support line, and the very helpful man (thanks Alan!) talked me through it stage by stage. If you go to the following page on the internet: http://support.apple.com/kb/TS5376 it takes you through the process. WARNING - it takes a little time!
Basically, the first thing you have to do is go to your Program Files and double click on your iTunes folder. There'll be a number of files with the suffix .dll - you need to move all the .dll files from that folder to your desktop - you can simply click and drag them on the desktop..
Next, uninstall iTunes - go to Control Panel / Add/Rempve Programs and when the list comes up remove iTunes. This will take a few minutes... Then reboot your computer.
Next, go back to Control Panel / Add Remove and Remove - IN THIS ORDER -
Apple Software Update
Apple Mobile Device Support
Bonjour
Apple Application Support
Reboot again!
Next, check in your Program Files that the iTunes folder is completely gone - if it has, great: if it hasn't, right-click on the folder and press Shift and Delete - it will say "Are you sure you want to completely remove the folder "iTunes"? Click on "Yes".
Reboot!
Then go to the iTunes download page and voila! It should download iTunes without any problems... well it did for me.... Good luck!

HT1926 My itunes won't open because it says "This application has failed to start because MSVCR80.dll was not found. Re-installing the application may fix this problem" Can someone help? I don't want to delete it altogether due to needing the phone backup

I was given notification to upload the latest version of itunes recently, so I clicked installed. However it has since corrupted my itunes and I get the error message:
"This application has failed to start because MSVCR80.dll was not found. Re-installing the application may fix this problem".
In poor timing, I have also accidently damaged my phone and have a new one to restore it to an old back up.
It is because of this I am reluctant to completely delete itunes off my computer and start again for fear of losing my back ups.
Is there another way to fix iTunes so I can open it again?
Thanks

Hey I finally got an older vesion of itunes to work!!! 10.7 x64 for windows 7
After uninstalling all apple products even quicktime
I had to delete everything from (program files, and program files x64, program data,)
And all downloads from apple, and I went in to search deleted other stuff from apple, and itunes
But definently not my itunes library and Playlist
Down loaded 10.7 x64 for windows 7, but checked (do not start when done)
Then I emptied my recycling bin and restarted my PC
I ran geek tech tool box same as reg cure pro, also PC Tools registry cleaner, and CC Cleaner
Then I emptied my recycling bin and restarted my PC
And wallah... It finally works, and I Love the older version anyways.

My iTunes will not start. The box on the error message APSDaemon.exe, And message says "This application failed to start because MSVC80.dll was not found. Reinstalling may fix." I did the reinstall and I get the same error.

Same problem today. Took five times to reinstall without any error messages. Apple has posted a way to fix and you should follow their's first. I finally got to upldate correctly by doing their fix but with one difference. I did the following:
1) Went to the C:\program files (x86)\iTunes and C:\program files\iTunes folders and moved every file ending in .dll to the desktop (even if two files in same location had the same name, just replace)
2) Restarted computer and still got error message
3) Uninstalled all apple programs possible in the following order......itunes, apples software update, apple mobile device support, bonjour, and apple application support.....all performed using the microsoft control panel
4) put all the .dll files on the desktop in the trash and emptied (this is a step apple support did not specifically put in their fix but for a final try I wanted to delete everything apple).
5) Restarted computer.
6) Re-installed itunes from apple website
No error messages during re-install and was able to open shortcut in one try. Even updated my ipad to make sure everything was working.

I tried to download the latest version of iTunes but failed half way through. It suggested that i reinstall we I tried. However, i now get this message which states "Application has failed to start because MSVCR80.dll was not found. Reinstalling the application may fix the problem"
I have tried this but with no success. I have therefore found that I cannot access my iTunes library at all now.
