Note: This also applies to Windows 98.

To correct this, these files must be manually deleted from your system using Windows Explorer or Find File. For more information on using these features, consult Windows on-screen help by choosing Help from the Start button.
The uninstaller also fails to remove all Windows Registry entries entered by the installer. The following entries remain in the Registry after running uninstall.

There may also be other remaining entries. While these items are not needed on systems no longer running QuickTime, there are no known issues associated with leaving them in the Registry. If you wish to remove them, this must be done manually using the Registry Editor.
NOTE: Editing the Registry is recommended only in cases where it is required to restore your computer to a properly functioning state, and when performed by an experienced computer user. In all cases, it is strongly advised to make a full backup copy of your Registry before making any changes to it.
