Thanks. After messing around with it, I think we'll need a network WIBU key dongle in order to have it work with Multiple users.
I had just the WIBU server component loaded on a test machine and the full client loaded on another system. After pointing the WIBU settings on the client system to the server, it sees it, but could not issue a license so the software started in demo mode.
I get the following error message on the server log:
Logon received from "ACRobur2156" at SERVER_NAME.
Cluster 1861:398085 not found.
