Has VB script been disallowed in version 25.2.14524.3?

This could be due to the M-Files API getting unregistered for some reason. Try the solution in this support article: No such interface supported (0x80004002) Restarting the server machine might also help if that's a possibility.

If you can't resolve it yourself, please reach out to your M-Files reseller for further troubleshooting.

Thank you for the suggestion. The issue has been solved.
