ArcGIS not recognizing a license that is authorized

[JosephLapczynski]

I have installed ArcGIS 10.1 (single use) and several licenses.  The one in question is Spatial Analyst.  When I open the ArcGIS administrator it says that it does have the license and that it is authorized.  However, when I am in ArcMap and try to use the Spatial Analyst tools it says that there is no license.  Does any one know how to fix this?

Thanks

Hi FarmerJoe,

Since it sounds like you have authorized the Spatial Analyst license, did you activate it in ArcMap?

-Open ArcMap
-Go to Customize > Extensions...
-Check the box for Spatial Analyst

After checking the box, try to use the Spatial Analyst tools again and see if you get the same error.

Thanks.

Thanks, I feel like I should have known that...
