I have read the threads on using 64 bit OS with Mach3 and understand the points made with great patience by Art. The parallel port cannot be used on a 64 bit system.
I want to use Mach3 in demo mode so that I can test G code programs, because I have W10 indoors where it's warmer but the licensed version running on XP is in the workshop where it is currently less pleasant. The demo version does not install the parallel port driver - so I should be able to install it on a 64bit W10 machine. I haven't had much success in achieving this so far - am I missing something here?
