We are currently upgrading our server and have found that MAS90 v 3.40 may not be compatible with Server 2003. We currently run Windows NT Server? We get an error from provide X that says "Can't open ACTIVATION key" Activation key could not be found. Is this true and if so what are supposed to run it on?? NT?? With Vista now being out there how long before we can't find server 2003?? any thoughts??
