This error can occur, if you have installed a different version of the CmWebAdmin service and the CodeMeter service.
This can happen, for example, if you had installed the complete CodeMeter Runtime in an old version (which includes CodeMeter and CodeMeter WebAdmin) and then later installed only an update of the Reduced CodeMeter Runtime (without CodeMeter WebAdmin).
In this case, it is best to uninstall all versions of CodeMeter Runtime found in the Windows Control Panel and reinstall the usual full CodeMeter Runtime Installer in the current version.
