Spatial Analyst License not working

[BretFischer]

I just installed the 60-day trial of ArcGIS Desktop on Windows 2013. I authorized every available extension for single use. When I try to run ANY of the spatial analyst tools I get this error:

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 license currently available or enabled.

I NEED this to work. Otherwise I'll just keep use QGIS.

Please HELP!

FYI, ArcGIS Administrator says my licenses are enabled

Go to ArcMap's Main menu at the top... Customize > Extensions.  Turn on the extension.  It should work now.

Well I feel dumb, lol.

Thank you

No problem. 🙂  It's actually a very common question.

Best,

What if you have Enabled the extension and its authorized, yet it throws the same error?
