I want to COMPLETELY uninstall Mastercam X from my system. How can I do that?

The first step is to use the Window Control Panel’s “Add/Remove Programs” option. Select the “Change/Remove” button on the Mastercam X entry:

Select “Remove” on the dialog that comes up, and follow the prompts.

Once you have removed the Mastercam X program, you will need to clean up any saved or changed files that the uninstall left behind. The uninstall will not remove any added or changed files – this is to prevent any data loss to you. Open up the Windows Explorer, navigate to the directory where you installed Mastercam X, and save all the files that you wish to keep. Once you have done this, delete the Mastercam X directory.

Next, you must remove the left-over files in c:\windows\system32. Be aware that Mastercam v9 relies on these files as well – deleting them will disable v9 until you reinstall Mastercam X. Delete these files:

MCBitmap.ocx

MCdescr.dll

MCInt.ocx

MCLstCtl.ocx

MCReal.ocx

MCView.ocx

MCXUtil.cpl

Lastly, you must remove the saved user settings in HKEY_CURRENT_USER. You must do this separately for each user on the system. Do not edit the registry if you are unfamiliar with the process – these registry settings have no effect on any part of your system. They are only mentioned here for completeness. Delete the following registry key:

HKEY_CURRENT_USER\SOFTWARE\CNC Software, Inc\Mastercam X
