Well, closing everything I could and disabling NOD32 AV seems to fixed the problem with the launcher not opening the installers the first try.
I tried poking around in my temp file while it was running, but I'm guessing your app has something against me opening my temp folder, or a command prompt
Still no go on the Game Jackal registration though. Still in trial mode (that trial/buy popup keeps kicking me out of game). I'm going to give the installer another go on a different PC later today and see what that does.
Thanks again.
