I have recently got a new PC so went to re-install Network Analyst.
I have ArcGIS 9.2 and I have the Network Analyst extension, I ran the user license and it gave me the authorization message.
I then expected it to be in the extensions (Tools>Extensions) but it's not.
I have a project set up already which has an ITN layer etc, and I added in the Network Analyst toolbox and tried to run some of the stuff in there but it says i dont have the required license (Network Analyst).
Any idea's what I am missing?
When you ran the install, did you do a standard installation? It should have installed all the extensions. Tack a look in your c:\programfiles\arcgis\bin directory and see if you have any of the Network Analyst dll's.
Just an fyi, my guess is 9.2 is nearing the end of it product life cycle, so support will begin to dry up.
