Checking Compatability

#1
Hi All, When installing the upgrade (Vista Home Premium to Windows 7 Home Premium) and it's checking compatability, I keep getting the message: "the following issues are preventing windows from installing - PerfectDisc." I wasn't aware I had this software nor can I find it when searching. Would anyone know if this is incorporated in to anything else but as I say I cannot find it.
Is there anyway round this apart from doing a clean install which I am not very confident in attempting. Thanks

The only PerfectDisc I know is a defragger, which is probably continuously monitoring the drive and dynamically defragging it. If you can't find the program go to run (start menu) type msconfig and look for it in the startup section. If you find it there, disable it, reboot and try again.

If that doesn't help take a look in the task manager in the processes tab, if you can see it, highlight it, end the process, then try installing again (without a Windows restart of course, otherwise the defragger will be reloaded again).
