Because I have a new PC, I run into the same trouble, CFS2 runs only in 16 bit and hardware acceleration does not work, then I installed my old CFS1 and… it works in 32 bit, -Installed CFS3 it works Full screen (3440 x 1440), FS2002/2004 both works in 32-bit mode. Only CFS2 Does not work in 32 bits.

Does anyone Installed windows 7 on an actual PC with CFS2 and then updated to windows 10 64bit?

I remember I had running Windows 7 with CFS2 without Problems, than came Windows 10 64bit, I updated and everything runs fine! -now there is the new PC and CFS2 went into trouble .

On My old Windows 10 64bit PC CFS2 runs still fine
