BBES does not launch when loading Electrical module

Question

Loading the Electrical module within ABD SS5 v 747, I get this error message : unable to launch Ole-Server - BBES.OLE 
 Thereafter can't register the file as an electrical design file although the "BBES Database Server - UK" window is opened... 
 No idea what causes this... Anyone out there?

Actually, finally found what the problem was. For some reason the registry keys were not in the registry. In the bin folder, all I needed to do was to double click on the BBES.REG to create the relevant keys.

I haven't seen that type of error in quite some time, but I think it typically refers to some type of permissions issue. Can you double-check that you have read/write permissions to your workspace's \medata folder along with C:\Program Files (x86)\Bentley\AECOsimBuildingDesigner V8i Ss5\AECOsimBuildingDesigner\ServerApp\bin? 
 
Also, from that last folder, what happens if you manually double-click on BBES.EXE? That's the database server for ABD Electrical.
