What version of Archicad are you using?
Since version 17 BIMx has been built into Archicad so no extra license is needed.
If you can start Archicad you should be able to save as BIMx.
Before that you had to purchase a separate license that was tied to a particular Codemeter/Wibu key license.
I don't use Codemeter borrowed licenses so I can not check the problem.
Maybe someone else that does use a borrowed license can check it out.
