Microsoft have updated security controls for RDP/RemoteApp sessions.
This warning will appear on the first login after the Windows update.
When prompted, users must select the following options:
✅ Drives
✅ Clipboard
✅ Printers
✅ Remember my choices for remote connections from this publisher
All other options can be left unchecked, unless specifically required.
Once confirmed, the warning should not appear again, and Dimensions will function normally.
