use the launcher at least once to make sure the game runs and trainer attaches.
from that point on you can close the game, then run the game normally through uplay or whatever to launch the vulkan version and the trainer will work.
launcher just needs to be used ONCE.
also, it's not URGENT to have a Vulkan version. The performance may be a bit better, but I highly doubt the game is on super shutdown mode in normal mode.
Either way, run the launcher ONCE to run the game.
Then close the game.
Then launch the vulkan version and try the trainer and it will work.
if the game has patched, which it has, then the launcher won't work.
You will need to verify your game using the UPLAY app, so that the game files are fully updated and not affected, then run the game WITHOUT the launcher and make sure it can run after verify.
Next, wait for updated trainer/launcher for new version, which will be out today.
Well that's fine and good, but since the game has anticheats, 4 executables, and I am in control of what is possible and what time I want to spend on this..
just RUN THE LAUNCHER AT LEAST ONCE..
close the game..
THEN you don't even NEED the launcher EVER AGAIN unless the game patches.
You can run whatever version you like.. just as I described above. I just tried it and the trainer works perfectly with the Vulkan version which you can run. I blew 15 minutes of my day verifying and testing all this, only to find that it works STILL just like I explained above.
