Startup commands give users the ability to control licensing.
Changes can made manually by editing the startup icon or by running the Mastercam Launcher
Right-click the Mastercam startup icon, select Properties and edit the Target line.

The standard Target line for Mastercam 2020 is:
C:\Program Files\Mastercam 2020\Mastercam\Mastercam.exe
At the end of the Target line, simply add a space and slash (“ /”), then the command. Repeat for multiple commands.
Example:
Customer license with Wire, Lathe, and Router not enabled (all other products will run)
- “C:\Program Files\mcam2020\Mastercam.exe” /noW /noL /noR
Licensing Overrides:
- /H Use a local HASP
- /N Use a NetHASP over the network
- /Software Use software licensing and search locally and on the network
- /SoftwareLocal Use software licensing in Local mode
- /SoftwareLan Use software licensing in Network mode.
Special:
- /NoHardwareAcceleration – Disable hardware acceleration
- /noREM – Suppress the dialog box that shows the applied commands
- /xm – Export the Mastercam menu resources to an .XML file for translator usage
