Datacentre can not find simulators

I am using Prepar3D V4 with ORBX and PMDG 737. The software is on a SSD drive E:\ not on the C:\ for performance reasons. However the Navigraph dataCentre does not find the simulator. Could not point to the right directory as there is no browse function, i am aware of. Any solution ? Thanks

If you are using P3D you can’t use the Datacenter yet. You need the FMS Data Manager instead.
