Download the Windows Installer CleanUp utility from the following page (use one of the links under the "DOWNLOAD LOCATION" thingy on the Major Geeks page):

To install the utility, doubleclick the msicuu2.exe file you downloaded.

Quit out of CleanUp, restart the PC. Now try another QuickTime install. Does it go through properly this time?
