A script started over COM has crashed with error messages like: - 'Communication with the Python background script failed'. - 'Could not start the script component'. - 'Could not find a matching script component for file extension '.py'.' - 'pythoncom error: ERROR: server.policy could not create an instance.'
- Register the COM server again: PTV Visum -> Help -> Register as COM server (In case this needs to be repeated, start PTV Visum as Administrator.) - Check the Python installation: Windows Start button -> Settings -> Apps -> Python -> Change -> Repair Python -> Finish (Older OS: Control Panel -> Programs -> Programs and Features)
