TS1717 error message that iTunes can't start because mcvcr80.dll is missing. How do I fix this?

after installing itunes update on windows 7 pc, get error message that program can't start because mcvcr80.dll is missing. How do I fix this?

Uninstall your existing copy of iTunes. Delete any copies of the iTunesSetup.exe (or iTunes64Setup.exe) installer files from your downloads areas for your web browsers and download a fresh copy of the iTunes installer from the Apple website:
http://www.apple.com/itunes/download/
(The current build of the 11.1.4.62 installer was changed a few days ago, which fixed the bulk of the reports of MSVCR80.dll/R6034/APSDaemon.exe/Error-7/AMDS-could-not-start trouble ... but the build number on the installer was not changed. So we're trying to make sure you do the reinstall using a "new good" 11.1.4.62 installer instead of an "old bad".)
Does the install with the new copy of the installer go through properly? If so, does that clear up the error message?

I just downloaded an update to ITunes this morning, and now I am getting an error message saying iTunes can't start because MSVCR80.dll is missing from my computer. What the heck happened?

Troubleshooting issues with iTunes for Windows updates - MSVCR80

I keep getting the message that iTunes can't start because MSVCR80.dll is missing. I uninstalled and tried reinstalling, but that hasn't fixed the problem.

iTunes was working fine until I got the message to update it. After the update won't function anymore (and Apple makes it impossible to get support on this).

Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features(Later)
Remove all of these items in the following order:
iTunes
Apple Software Update
Apple Mobile Device Support (If this won't uninstall press on)
Bonjour
Apple Application Support
Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.

Should you get the error iTunes.exe - Entry Point Not Found after the above reinstall then copy QTMovieWin.dll from:
C:\Program Files (x86)\Common Files\Apple\Apple Application Support
and paste into:
C:\Program Files (x86)\iTunes
The above paths would be for a 64-bit machine. Hopefully the same fix with the " (x86)" omitted would work on 32-bit systems with the same error.

I researched the advice on the link provided by b noir as well as very similar advice from apple support: http://support.apple.com/kb/TS5376. It worked for me (for now).
Some things of note:
I did all of the things requested by the link I provided
My computer WOULD NOT uninstall Apple Mobile Device Support. I had to manually remove the folder (also as instructed by the url)
I also uninstalled MobileMe. Was a little different than removing the other apps. Follow instructs provided here: http://support.apple.com/kb/HT2992
I did not uninstall iCloud
I have to admit it was a bit scary removing all those things. Is important to note that when re-installing Apple, follow steps to do so as Administrator (the right-click thingy and whatnot).
Hope this helps!

Error Message: "The program can't start because QTCF.dll is missing....."

Full error message: "The program can't start because QTCF.dll is missing from your computer. Try reinstalling the program to fix this problem." I can't start iTunes because of this error. Any advice on what to do?

I have discovered the reason this occurs. It is because the PATH in the environment settings no longer has the path to C:\Program Files (x86)\QuickTime\QTSystem which is where the .dll lives on a Windows 7 computer. Close the application giving you this warning if it is still open and use the following 10-step process to fix this:
1. Search for the path to the QTCF.dll and upon finding it, copy it (Highlight it in the explorer address bar and press CTRL + C.)
2. Open the control panel.
3. Choose System and Security from the left.
4. Choose Advanced system settings from the left and a dialog window pops up with the Advanced tab selected.
5. Click the Environmental Variables... button near the bottom of the dialog box.
(This opens a dialog box with 2 sections: User variables and System variables.)
6. Scroll down through the System variables section so that you can select (highlight) the Path variable in the left column.
7. Click the Edit... button which opens a small dialog box and highlights the entire Variable value.
8. Click once in the Variable value (to deselect the value so you don't mess it up) and then press the end key on your keyboard (to move your cursor to the last character of the very very long string in the text box).
9. Paste (keyboard combination CTRL + V) the path to the QTCF.dll you copied earlier, and add a semi-colon, for example:
C:\Program Files (x86)\QuickTime\QTSystem;
(Note that you don't need a trailing / or the actual .dll name in the path, but be sure to add a semicolon to the end of the path name you paste.)
10. Click OK on each of the 3 open dialog boxes.
There is no need to reboot your computer. You only need to restart the application and ensure that it starts without the warning that the .dll can not be found.

Despite unistalling and reinstalling iTunes, I can't load the program. The error message "the program can't start because MSVCR80.dll is missing from your computer."

Despite trying to unistall and reinstall iTunes, I continue to get the message "the program can't start because MSVCR80.dll is missing from your computer. Try reinstalling the program to fix this problem."

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.

My Itunes won't open. When I click on it I get error message: The program can't start because MSVCR80.dll is missing from your computer.

The first error message is: itunes.exe-System Error: the program can't start because MSVCR80.dll is missing from your computer. Try reinstalling the program to fix the problem.
The second error message says: itunes: itunes was not installed correctly. Please reinstall itunes Error 7 (Windows error 126)
I have reinstalled several times and the same thing keeps happening. Does anyone know what to do?

Ralph, both links you've posted point to the same place!
Ah, I see the second one is meant to lead to Tony's tip: https://discussions.apple.com/docs/DOC-6571
That one applies for certain launch errors that can occur when iTunes has otherwise installed successfully. I've addressed the same issue in the first box of my tip.
What would be interesting to know is if Aswim does indeed have QTMovieWin.dll in their Program Files\iTunes folder, and if removing it allows iTunes to launch? It would seem that different error messages may be thrown up by different versions of the file on different versions of the OS. Perhaps many more people have been doing a complete rebuild than needed to.

Error message states iTunes could not connect because paring record is message is missing, how do I fix?

Sometimes rebooting your PC can clear this error message. You might also want to try plugging the iPod into a different USB port as well.
Others have been able to fix it by unplugging their iPod from their PC, signing out their Apple ID on their iPod Touch, signing back in and reconnecting it.

Upon trying to reinstate I am thwarted with this: "iTunes was not installed correctly. Please reinstall iTunes. Error 7 (Windows Error 126)

When opening iTunes I continue to get the same messages, 'The program can't start because AVFoundationCF.dll is missing' and 'iTunes was not installed correctly. Error 7 (Windows error 126)' I've uninstalled, reinstalled many times - nothing! help please.

When opening iTunes on my new Windows 7 PC I continue to get the same messages, 'The program can't start because AVFoundationCF.dll is missing' and 'iTunes was not installed correctly. Error 7 (Windows error 126)' I've uninstalled and reinstalled many times to no avail, even tried it on a different user account and still nothing. I recently installed Panda Internet Security 2012 (about 12 days ago), initially iTunes worked fine as usual but within the last few days I've been unable to open it with the same messages appearing. I've read through some of these pages and tried everything that's been advised, uninstalling and reinstalling while internet and laptop security is swithched off, downloading tools to completely remove anything related to iTunes, tried it in Safe Mode, nothing has worked. I've also noticed that in the start menu when I click on iTunes, it says '(empty)' where it should have the logo and ability to start the program, does this mean it doesn't download + install properly each time I've tried? Any help would be enormously appreciated.
