I recently installed the new ArcGis (10.5) on our system. ArcGis is working perfectly well, but since then FME isn't able to execute ArcGis related (GeoDatabase) tasks. The Error call is: Unable to check out an Esri license. Please ensure ArcGIS is correctly licensed and that there are available licenses.
Is this a known problem and what can I do to solve it (except for waiting 2 weeks for the new FME release). The only thing I can think of is reinstall the older ArcGis.
