When I tried to run it using an icon it too gives me an error. I tried to run it using Control Panel. This gave me a different error. It said "An exception occured while trying to run "C:\WINDOWS\system32\shell32.dll,Control_RunDLL "C:\WINDOWS\system32\QuickTime.cpl",QuickTIme".
This has all been
perfect information, mibster. Every symptom is consistent with another application (other than QuickTime itself) having dropped old QuickTime componentry in a non-standard location on the PC. So let's go looking for that.
You'll need to make sure you are set up to view hidden files and folders in XP.
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.
