https://bugs.winehq.org/show_bug.cgi?id=38493 --- Comment #3 from Olivier F. R. Dierick <o.dierick(a)piezo-forte.be> --- 64-bit is a requirement for the game. I modified the bug report to reflect this. I tried anyway out of curiosity. Wine ends with this expected error message when the launcher is run from a 32-bit wineprefix: err:process:create_process 64-bit application L"C:\\Program Files\\Rockstar Games\\Grand Theft Auto V\\PlayGTAV.exe" not supported in 32-bit prefix I tried to run subprocess.exe itself from the 32-bit wineprefix, since it is a 32-bit executable, but it has to be launched from the game launcher otherwise it exits instantly without doing anything. Note that I could install the game in the 32-bit wineprefix because the installer is 32-bit and it doesn't check if the system is 64-bit when installing the game. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
