This is an issue that a Lot of people have been running into- well... eveyrone who tries to use it that is. For some reason NProtect Gameguard does not work with windows 7- this means that any games that use it to prevent exploitation also do not work, because they will only run if they detect it in the background. It runs kind of like a rootkit i'm told, and it works on windows XP and windows Vista. I've tried installing it (it is included with my game, gunz the duel (gunz.ijji.com)) on multiple security setups- and nothing. There have been a few people who have reported no problems, but I've tried it on both 32 and 64 bit builds of windows 7- and nothing. I know that nothing is officially supported, and nothing is guaranteed to work- but does anyone know of a workaround that I could try? I've been keeping an eye on google for several months, and nothing has come up.
