I am unable to re-install itunes due to an Error 2

Then when I press ignore, it gives an Error 2 (Apple Application support was not found).

Let's try a standalone Apple Application Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of the issue.

Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:

http://www.apple.com/itunes/download/

Download and install the free trial version of WinRAR:

http://www.rarlab.com/

Right-click the iTunesSetup.exe (or iTunes64Setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").

Go into the folder and doubleclick the AppleApplicationSupport.msi to do a standalone AAS install.

Does it install properly for you?

If instead you get an error message during the install, let us know what it says. (Precise text, please.)

I've done what you said to do because I was getting the same Apple Application support message, but now when I try to redownload and install iTunes, now I get a message that says "The program can't start because MediaAccessibility.dll is missing from your computer. Try reinstalling the program to fix this problem." I've tried uninstalling and reinstalling again numerous times, but nothing works, I still get the same message. Any advice?

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

Even though you're getting a different error message, try the following user tip:

iTunes for Windows 11.1.4.62: "The procedure entry point: ?videoTracks@QTMovie@ [...] could not be located ..." error messages when launching iTunes

Was there a QTMovieWin.dll in your iTunes program files? If so, does dragging the file out onto your desktop get rid of the iTunes error?

🙂 You're welcome. Glad you got things sorted out.
