many thanks. (Haven't seen one of these in a while, and now suddenly there's two in one day.)
I think some other application (apart from QuickTime itself) has stashed old QuickTime componentry on the PC in an unorthodox location. (Codec packs and video converters are the usual suspects with that, although some games might do the same.)
So we'll go looking for the older QuickTime componentry in the most common locations for it to be stashed.
First we'll need to change some view settings.
In your Start menu, open Computer.
In your Organise menu, select Folder Options.
In the View tab, make sure that "Show hidden files and folders" is selected, and Hide extensions for known file types is unchecked.
Click OK.
Now in Computer, open your C:\ drive (or whichever drive you have your operating system installed on).
Open the "Windows" folder.
*If you have a 32-bit version of Windows,* open the "System32" folder.
*If you have a 64-bit version of Windows,* open the "SysWOW64" folder.
What files and folders can you see in there with QuickTime in the title? (In a standard installation of Quicktime you should be seeing precisely two files ... QuickTime.qts and QuickTimeVR.qtx ... and no QuickTime folders whatsoever.)
