I have Mach3 installed and running on my development PC which is windows 7 64bit, however I have not connected to a CNC controller. So I guess some 64bit systems it may work.
This might be a bit of a pain to do (and may not work) but you could try running an emulator so the 64 bit pretends it is a 32 bit PC:
From Microsoft: "WOW64 is the x86 emulator that allows 32-bit Windows-based applications to run seamlessly on 64-bit Windows"
https://msdn.microsoft.com/en-us/lib...=vs.85%29.aspx
Or you could try running in XP mode (I have used this to run programs that would not run on WIN7):
Install and use Windows XP Mode in Windows 7
I wouldn't think you could damage your PC port or controller, but I'm not 100% sure (maybe 95% you will be ok) so be careful (don't blame me if something goes bang).
