Solution for this problem:
1. Go to C:\Program Files, then delete the entire QuickTime folder.
2. Click Start - Find/Search - All Files And Folders, select the hard drive ( C: ) to look in, type in QuickTime, then click Find/Search. when the list of files appear, right-click on and delete all the ones that you confirm are associated with QuickTime.
3. Click Start - Run, type in REGEDIT, then click OK. Click the + in:
HKEY
LOCALMACHINE
Software
In the Software sub-menu, right-click directly on the Apple Computer entry, then click Delete - Yes.
(Note: If you click the + in the "Apple Computer" entry, you'll see "QuickTime" listed there)
After this, just to make sure everything was gone, you go to control panel ->remove programs, and quick time still showed up, but when you click on uninstall, the fatal error message won't show up anymore, and it will be completely removed.
You must also delete everything that has to do with apple, and ipod, itunes and all of that in the process.
They also mentioned the program Ccleaner, which you can download from
