Doesn't mean that it does a clean uninstall of the old version. More often than not, old registry entries are left behind that refer to stuff that isn't there anymore. Almost every program I've ever seen does that, or leaves some uninstaller reference issue or another. I clean those out with Ccleaner.

One good example is F-Secure internet security software, if you uninstall that using the uninstaller that came with it, it leaves a crapload of entries, some of which contain functionality. If it goes kablooey on you and those are not removed, reninstalling the software will not get rid of the problems since they still refer to the old corrupted stuff. So you need to use their own separate removal tool to get it off the machine clean.

A software package the size of the CCC and supposed to run on different hardware configurations in several varieties of Windows, damn straight I will NOT trust it to do a clean removal of old software before installing new stuff.

One of the reasons my computer needs so little maintenance is because I'm so anal about doing things right from the get-go and not trusting too much. Learned to act that way from experience.
