I dont know if it was adding each EXE in the folder to my allowed apps list or what, but its finally working. Thank you for your advice

@AndrlCh said in Cant start on steam. GameGuard problem?:

Have you set your "steamapps" and/or "PHANTASYSTARONLINE2_NA_STEAM" folder as an exclusion in Windows Security? Even if you have it deactivated, Windows Security (and any other anti-virus or firewall) can sometimes kill Gameguard.

When i checked, it looked like it did that automatically. Is there a specific somewhere or something i havce to do for gameguard in particular? would it be under a different name? I've already allowed the whole folder past my AV

I just downloaded the game on steam, but it wont let me on. The launcher starts, it updates any everything, but when i hit Start Game, it shows the GameGuard window for a split second and closes outright. I've tried deleting the windows store version, i've tried messing with settings, but i dont know why it keeps failing to launch.
