License error -209 (No license valid for the specified feature)

Modified on Thu, 24 Aug 2023 at 09:53 AM

Possible causes: 


1.If there is a valid interface license that is also valid for MegaCAD 2023 and Parts4CAD,the -209 error message may not be the "originating message" of the system.


You may have only one interface license in use and are trying to use the interface on multiple workstations in parallel.The interface then cannot be used on multiple workstations at the same time.In addition, there is an expired trial license on this computer, which then triggers error -209.


2.It could also be that the registration of the online license does not work properly and the MegaCAD software itself is started e.g. via a test or offline license.



To check both, we need the LOG file (MPSER.LOG) of the MegaCAD license server.

Default path: C:\Megatech\MProtect2\MPSERV.LOG
