TOOL NOT LICENSED - ERROR 010096

[AaronKeillor]

Here's a handy quick fix if anyone is getting the ERROR 01009 warning when they try to use extensions from ArcToolbox (e.g. Spatial Analyst)
___________________________
TOOL NOT LICENSED

Unable to execute the selected tool.
You do not have the necessary license to execute the selected tool.
ERROR 010096: There is no Spatial Analyst currently available or enabled.
___________________________

In ArcMap 10.1

Select Customize (from the top of the screen)
In the Customize menu, select Extensions
Check the Extension (Spatial Analyst)

* Spatial Analyst is now enabled and you should not get that message any longer (provided you already had it setup correctly in Administrator)

- hopefully that saved a few headaches for future ArcGIS students -
