Hi Janice -
This is not an "official" statement (sorry)... it's just my preference when installing a newer/different version of any software or re-installing software that's not functioning properly... I'm not saying it's necessary to do this.
I use dedicated uninstaller software (Revo or similar) to completely remove the previous version, before reinstalling. That way, all registry footprints are removed. The Programs & Features in Control Panel doesn't do this.
Maybe an "official" CyberLink statement will pop up soon.
Cheers - Tony
