I have a problem with one client checking out a licence for offsite usage. We have a Zoo 6 server running without problems. Other clients can use or checkout licencences as described but one client can not. He does not even see the licence in the Rhino options window. Nevertheless using the licence is possible as I can see in the Zoo admin window. I deleted and re-installed Rhino and all other McNeel applications on the client but the behavior remains.
Any ideas what to check or to modify?
