Some time ago I had a trial copy of Cyberlink YouCam which during the trial period I uninstalled. Last week I purchased a copy of this programme but when I try to install it I get the message that YouCam has been found on my computer and do I want to remove it: If I select Yes the message appears again and again and again non stop until I select No. I have ran Registry Checks and also carried out a deep search of the computer but can find no trace of YouCam either on the Hard Disk or is the registry. Is there any method at all which will either point me to where this remainder of the programme is or how to get rid of it? All help appreciated.
