I am installing Mach3 on a Windows 7 64bit PC and I get a screen that says "No driver sensed installed. Run driver test."  After hitting the yes button it goes with no noticeable delay to the installation finished screen but the program is not engaging the steppers.  I've retried from the DriverTest.exe file with the same result.  Any ideas about the cause of the problem?

So I just read the post about the parallel port driver not working with a 64 bit system.  Can someone explain the work arounds for that situation?

Get a 32 bit OS or an outside motion controller that works with Mach3.
