DS5：Cannot checkout an uncounted license within a Windows Terminal Services guest session.

Thanks for your update. May I know, are you accessing a machine over a remote desktop session? Referring to error message ( License Issue: Cannot checkout an uncounted license within a Windows Terminal Services guest session ) looks like you using remote session.

From my understanding, your license is a fixed type license. Fix type license can’t support this feature. If you are accessing a machine over a remote desktop session, you need a Floating style license.
