I just purchased the mach3 add-ons. I tried to open the .dat file but it says I need to go to control panel and create an association for it. I have no idea what to do. I know how to go to the file folder options in the control panel, but after that I am lost. I do not have mach3 installed on this computer so I need to save it and burn it to a cd and then load it to my computer that runs my mill.
Please help!!
