Cannot Uninstall Quicktime

Doublechecking something, Gryz. Is your iTunes also currently failing to launch? If so, is it a similar sort of error-message-free launch failure?

Before I uninstalled it I got error messages saying Quicktime was not up-to-date, which started me down this path.

Okay ... They aren't classical versions of the symptoms (still, those change on a regular basis), but you're getting enough things going on here to make me suspect that some other application (other than QuickTime itself) has stashed old QuickTime componentry down in your system files. (That can cause QuickTime launch and install trouble, and also those "out-of-date" messages when launching iTunes.)

So we'll go looking for the older QuickTime componentry in the most common locations for it to be stashed.

First we'll need to change some view settings.

In your Start menu, open Computer.
In your Organise menu, select Folder Options.
In the View tab, make sure that "Show hidden files and folders" is selected, and Hide extensions for known file types is unchecked.
Click OK.

Now in Computer, open your C:\ drive (or whichever drive you have your operating system installed on).
Open the "Windows" folder.
*If you have a 32-bit version of Windows,* open the "System32" folder.
*If you have a 64-bit version of Windows,* open the "SysWOW64" folder.

What files and folders can you see in there with QuickTime in the title? (In a standard installation of Quicktime you should be seeing precisely two files ... QuickTime.qts and QuickTimeVR.qtx ... and no QuickTime folders whatsoever.)

In the System32 folder (I am using the 32-bit version of the OS) there is a Quicktime folder with nine different ".qtx" files in it.

I think that's our trouble.

Drag that entire QuickTime folder out onto the desktop. Are you able to launch the QuickTime Player now?

If so, reinstall iTunes. Can she launch without the "out-of-date" messages now?

🙂 Thank you kindly, Gryz! Glad you're up and running again.
