Having just played Serious Sam First and Second Encounters HD I thought I would try Serious Sam 2 again. I then remembered the problem I had before. When playing under XP everything was fine but playing under Vista 64 bit and now Windows 7 64 bit I get really cheesed off when at the end of every level the armor reduces to zero and health reduce to 100. Having Googled without finding a solution or even without finding other users with the problem I am stuck
Unfortunately Oldjim you'll either have to dual boot XP with Vista 64 Bit or Windows 7 64 Bit and play all your old games in Windows XP those that you know work fine in Windows XP, and just use Vista/Windows 7 for all your other stuff.
