ArcGIS Desktop error 010096, Tool Not Installed error there is no Spatial Analyst license available when attempting to use Zonal tool. Installed Zonal tool by opening the Customize menu and choosing Extensions.
Now when I open the Zonal tool the error 010096 has gone away but the tool does not load or start.
ArcGIS Administrator says that there are licenses for the Zonal tool available.
Did I miss a dependency for Spatial Analyst Tools or specifically for the Zonal tool?
Are you referring to the Zonal Statistics tool?
The error message is not what you say it is:
010096 : There is no Spatial Analyst license currently available or enabled.
My guess is the tool is running in the background. You can see the results in Geoprocessing / Results.
To see it run (this is the setting I prefer) go to Geoprocessing / Options and uncheck the Enable Background Geoprocessing box.
No error messages? This is kind of strange. I'm wondering if there is an issue with your inputs. The zone polygons and raster should be in the same coordinate system.
Note that there are many zonal tools, please be specific.
