OPSE project on the network

Hi to all

How can we place OPSE workspace on the shared network directory?

I have already read this article:  "How to configure OpenPlant Modeler to Use Workspace from Shared Location".

How to place without drive mapping? We found the way, writing such path to msdir.cfg

_USTN_INSTALLED_WORKSPACEROOT=\\\\servername\\catalog1\\catalog2\\catalog3\\WorkSpace/

Replacing any double quotation mark with four quotation symbols (we redouble quotation marks). 

In this case OPSE launches fine, but we have error opening Briefcase database.

Does anyone know how to do that?

Thanks to all
