Thread: FB & Win7 32bit

For reference, I can control a FB from inside a 32bit instance of Windows XP, running in Virtual PC, on top of Windows 7 64bit. I just told Virtual PC to attach to the USB device, and everything acted normal after that.

Everything else is written in .NET so it should work on any OS or system that can run .NET.

DirectX on x64 has been my biggest issue on this x64 Windows 7 box, but I just found out how to resolve that tonight. By default, Visual Studio compiles to a target platform of "AnyCPU", which means the app runs as 64 bit when on a x64 box. This causes a problem if it calls any .dlls that are 32 bit only. The solution is to change the compile options so the target platform is x86. I am now able to run an app I built that uses DirectX.

If you change the same thing, you should be able to run MDX on x64 machines. That just leaves the drivers. I have no clue how drivers work, but if you compile them, maybe this option will allow them to work on x64 machines as well.

Well, good news. I now have basic USB communication between the Fusion Brain V4 and Windows 7 x64. I havent tested its backwards compatibility with x86 yet though, so hopefully that isnt broken .

Now I need to update the rest of the software.
