iTunes suddently stopped launching day before yesterday and I get a message which explains that "windows data protection" stopped this program from executing. I tried reinstalling iTunes with the same result so I decided to uninstall and reinstall. Uninstallation of iTunes was successful but I could not uninstall Quick Time as is neccessary for a complete new removal/reinstallation. Instead, unintstallation of Quick time starts and proceeds for a while and then "rolls bacK', declaares a "fatal error" and exits.
🙂 Immaculate detail, thanks david.
Taken as a whole, your symptoms suggest that some application (other than QuickTime itself) has stashed old QuickTime componentry in unorthodox locations in your system files. (It can also cause "Fatal error" uninstall trouble for QuickTime.)
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 options on the PC.
1. Open My Computer from the desktop or Start menu.
2. In the Tools menu, click Folder Options.
3. Click the View tab.
4. In the "Advanced settings" pane under "Hidden files and folders" make sure that the "Show hidden files and folders" option is selected, and the "Hide extensions for known file types" option is unchecked.
5. Click OK.
Now in My Computer, open your C drive.
Open the "Windows" folder.
Open the "system32" folder.
What files and/or folders can you see in there with QuickTime in the file/folder name? (In a standard installation of QuickTime, you should see precisely two files ... QuickTime.qts and QuickTimeVR.qtx ... and no QuickTime folders whatsoever.)
