etaoin, I have three files from the QuickTime 6 package showing up as damaged in my "Downloaded Program Files" window: two QuickTime Plugin Class Files and one QuickTimeCheck ActiveXControl Files, but they all show up as "ActiveX" files in their respective "preferences". The "6" is an upgrade beyond my Windows Media Player and RealPlayer capabilities, so that may be why QuickTime, even though supposedly uninstalled, is taking precedence. And may also confirm your explanation for the problems. There are still 20 files from the QuickTime package showing up on my system even after uninstalling (the window warned not to uninstall all the files or problems could result, and showed two 'remove' buttons, suggesting the more limited one). Still, the remianing files seem to include the main QuickTime File of 4,370 KB and other major KB files that I assume should have been removed when uninstalling the program...so I don't get it???
The window in the "Add/Remove" section said the uninstallation was complete.
