I am trying to upgrade my NT 4.0 clients from 6.0.2 to 6.1.1 and am having problems. I keep getting the message "Network resource is unavailable...Please select path to Networker.msi" When I do this it does not recognize this as the correct path to the installer. I have tried doing a partial uninstall but did not fare any better. Does anyone have any insight into known problems with this version upgrade and how to fix them? Thanks
