I am unable to install Powerdvd 7.3 now. I had done before though but what with me sodding about with trying to get HD DVDs working I can't install it any more. It comes up with this screen: This setup will perform an upgrade of ". Do you want to continue? I've tried Googling a solution but no luck. I've tried trying to completely wipe out all traces of cyberlink/pdvd ,and when I thought I had it still pops up on install. I realise it may seen trivial but it's completely winding me up. Does anyone know where I can get a decent copy of it? I can't seem to buy it anywhere.
