Hi Everybody,
Had the same problem not being able to launch the X64 version of the executable.
The solution as far as I’m concerned was to simply delete de profile Nvidia created in control panel for the Falcon Bms executable. Not the launcher.
From then on I was able to launch the X64 Falcon exe.
A friend of mine had the same issue and he did fix it the same way. So maybe a solution after all….
Brgrds,
