Answer: To successfully remove QuickTime for Windows, whether you use the uninstall program or the Add/Remove Programs control panel, the Control Panels window needs to be closed. This is because both a QuickTime, and QuickTime 32 control panel is considered active by Windows, whenever the Control Panels window is open. Close the Control Panels window after opening the Add/Remove Programs control panel or before running the Uninstall QuickTime application.
