Make a new folder Mach3 on the hard drive then copy the fresh Mach3 that you just downloaded to that folder on your C drive. Run the install then copy the XML and Mach1lic.dat files on the zip to the Mach3 folder on your C drive. Hopefully you should be up and running. There are numerous ways to do this just don't lose the Lic.dat file that is you holy grail the rest can be duplicated. I have had Mach lock up on me,and do crazy things but by saving all my data I can be up and running after a glitch. There is a optimization procedure on there website it help things running smoothly. I have no other programs except MasterCam on my shop computers. I don't run a lathe just a Big Bridgeport Boss 5 using Mach3. I have confused myself hopefully this helps.
Again don't lose that Lic file.
