Since CodeMeter version 5.10, license access during a remote session to server operating systems (e.g. Windows Server 2012, Windows Server 2016, or Windows Server 2019) is only possible, if the number of licenses is >0" and not Local AccessOnly".
If you still try to access a license with license number=0 or "Local AccessOnly", the error "Remote access is not allowed for this license, error 239." appears.
If the remote desktop connection is established on non-server operating systems (e.g. Windows 7, Windows 8 or Windows 10), a license with number of licenses =0 or "Local AccessOnly" can be used in this session.
