I just installed ArcView w/ single use license, and I'm having issues running tools from ArcMap. If I launch ArcCatalog I can navigate to a tool (I'm specifically trying to use Contours, and Aggregate) and run it without a problem, but if I do the same in ArcMap I get a message saying I don't have a license. I can run tools that don't need an extension license (Raster conversions, for instance) without a problem from ArcMap.
I assume I just missed something obvious, but can't figure it out.
