Can't you just uninstall and delete (except what you want to save of course) the Mach folder on the C: drive? Then reinstall..
You are loading it onto the C: drive, correct?
Thanks for the reply, but I did that yesterday when Hood was trying to help.
I deleted everything associated with Mach3 including going through the Registry, I installed to C:\Mach3
In Properties for this DriverTest.exe file
Size = 421 KB (431,616 bytes) and
Size on disk = 424 KB (434,176 bytes)
Could someone validate this for a version that shows Mach3 in the Title bar?
I suspect the old Mach2 version is in the installer.
