The new installer doesnt seem to do anything, MTA is running in the background, if that makes any difference and is terminated when i close out the single player game.
I'm currently using a folder on my secondary drive with full rights access,x:\MTA the SA install is located x:\MTA\GTASA (as far as windows sharing and security tab is concerned) I have also tried installing MTA to program files (x86), as well as the normal steam\steamapps\common\GTASA for the SA install (switched to the aformentioned x:\MTA after some time troubleshooting the issue)
I'm running the steam version using the nocd 1.0 exe. I can run either single player location using the cracked exe with or without steam running. Not sure if others that are having the issue are running the steam version or the origional 1.0 .
