Recommended to run prior to updating Calcomp driver in NT 4.0.
Used to remove previous installed Calcomp drivers version 5.0 and the
current 95/NT4.0 version 4.20. It is not selective and will remove all
Calcomp devices except CCl600. Run Ccleannt.exe and it will extract
to ccp subdirectory. Run the Calcomp Remove NT executable and it will
request a reboot. After the reboot the Calcomp printers should be gone
and the installed files also.
