waltc: No, this forum is for all of the BT games...you just have to be specific about the one you mean. But--I have no problem with the Trilogy on Win10x64, either.
theduke66: Good for you. your posts were real helpful.
Well, the only thing I suggest is to make sure you have installed the latest DX9.0c runtime from Microsoft, found here:
https://www.microsoft.com/en-us/download/details.aspx?id=34429 If that doesn't help/fix it, then all I can think of for you to do is to make sure you are running the latest nVidia driver package for your system.
I realize it's not much help, but without your machine sitting in front of me there is, I'm afraid, very little else I can suggest.
One other thing--as I think of it--try disabling your AV program--and then running the game--sometimes an AV program can produce a false positive and completely cripple a game--happens regularly, I read about it often. My advice there is that if you are running an AV program besides the one that comes with WIn10, Defender, uninstall it and stick with Defender--it's all you need and has a very low incidence of false positives.
Wish I could do more, but telling you that the game runs fine on Win10x64 merely lets you know that the reason it won't run isn't because of your Win10 installation--if that was so then *nobody* running your build of Win10x64 could run the game. So, the information lets you know to look *elsewhere* for a solution--that's the value of the information. Again, this is all I can think of atm...Good luck!
