@night_dragon_on thank you for your response. as i said i'm on mac, and appears to me the only way to launch the game is through WGC. and somehow only after the last wot update i started having the problem of xvm not able to start because of the 64bit issue, as i saw the same error message in python.log. do you know by any chance on mac how i could make launch the game in 32bit? again, thanks much for your response.
