You can remove the entry of the expired, borrowed license from the dongle by using the --lt-cleanup option, which is included in our CMU tool.
The CMU tool is (default) located in
C:\Program Files (x86)\CodeMeter\Runtime\bin
To do this, issue the following command in the command line:
.\cmu32.exe --lt-cleanup --deleted --serial <serial number> --firmcode <FirmCode> --productcode <ProductCode>
Use cmu32.exe to address the tool. This is followed by the option --lt-cleanup (LicenseTransfer-Cleanup). Then enter the action that the cleanup should perform. There are different actions to remove an expired entry --deleted. Then, of course, you have to tell the tool which ProductItem, in which FirmItem, in which container you are dealing with.
You can also see a brief explanation and a representation of the syntax if you send cmu32.exe -? in the console to call up the built-in help.
