I built myself a Delineated Watershed tool using Model Builder however when i go to execute the tool in the tool box it read the error error 010096: There is no Spatial Analyst license currently available or enabled. My extension for the tool is turned on and valid because i am able to use any of the individual spatial analysis tools, its just my individual tool that is giving this error.
When not within Modelbuilder, all spatial analyst tools will work. WHen i put one spatial analyst tool into modelbuilder and create a tool it shows up as a locked tool in the toolbox.
So i was able to solve this myself and since ive seen other people have had this problem ill answer despite how simple it was. Just take note that just because you have an extension on in ARCGIS doesnt mean it is on in arc catalog as well...
