Removing an evaluation license

To remove an expired evaluation license causing issues with Muk3D, you can use Catapult by running Licensing/Remove evaluation license. Select the license to remove (note that removal is permanent) and confirm. Alternatively, use CodeMeter Control Center to locate and remove the license, or as a last resort, use the CodeMeter Command Prompt

Remove License

If an expired evaluation license is on your system (either from evaluation or training), it can cause problems with Muk3D.  Catapult will keep flashing warning messages that the licenses aren't valid and eventually it will shut Muk3D down.

There are three ways to remove a license.

Through Catapult

Run the command Licensing/Remove evaluation license.  This will bring up a dialog listing any evaluation licenses installed on the computer.

Check the box in the Remove column for any licenses that you want to remove.  Once you hit OK, it will prompt you several times to check you really want to do this.  Evaluation licenses can't be reinstalled, so if you remove it its gone forever.

Through CodeMeter Control Center

CodeMeter Control Center shows the CodeMeter licenses that are installed.  A license can be removed by clicking the Remove license button.  However on many systems this license is disabled, so this method may not be applicable.

Through the CodeMeter Command Prompt

This is the last resort way of removing a license since it involves the MS-DOS command prompt. Open the CodeMeter Command Prompt by going to Start/CodeMeter/CodeMeter Command Prompt.

The command is:

cmu32 --delete-cmact-license --serial XXX-XXXXXXXX

Where the XXX-XXXXXXXX is the serial number of the license, which can be copied from the CodeMeter Control Center license list.  Also note that there are double-dashes before delete and serial.
