Any idea? Draftsight won't start after instalation. Windows 11.

1. I've installed Draftsight and entered activation key during install (bought via online store)
2. Program won't start - two message boxes pop-up:
   1. "Failed to load modules. The application will be closed. Please reinstall the application." [OK]
   2. "The following modules were not properly released: C:\\Program Files\\Dassault Systemes\\DraftSight\\bin\\RecentDocumentBrowser_25.5_17.tx" [OK]
3. Reinstall won't help (Repair mode)
4. Cannot do a clean installation as there's no way to release licence as program won't start
5. Support page for Draftsight is don't work. Didn't work before weekend, don't work now:
