[GIS] Why do some ArcToolbox tools have red x over them

arcgis-10.2arcgis-desktoparcgis-license-managerarctoolbox

Why is it when you right-click to open some of the tools on the ArcToolbox, such as the TIN to Raster Tool for example, an image of a red x immediately appears over the tool icon? The tool dialog then never opens. What am I not understanding?

I'm using ArcGIS 10.2 for Desktop.

Best Answer

The tool is not licensed. This may be due to your ArcGIS license, or potentially an extension that is not turned on/licensed. In the case of TIN to Raster Tool, it would be the 3D Analyst extension.

While this article is a little out of date, it may give you some ideas of what you should do in order to see if you can get it licensed.
