[GIS] Results in ArcGIS search window do not bring up tool when clicked

arcgis-10.3arcgis-desktopsearch window

I have been unable to use the links resulting from a tool search to open a tool. When I click the link for the tool nothing happens – no tool is retrieved.

This problem is only occurring with tools and not maps, data, and images. Also, this problem occurs with every tool I have tried to open from the search window. Tools open regularly from toolbox window.

What do I need to do to restore functionality to the search window?

In ArcCatalog go to Customize --> ArcCatalog Options and on the General tab make sure Toolboxes is checked. That's what worked for me. I had unchecked everything to clean up my Catalog Tree and that's when the problem started. I ignored it for a day and then remembered what I had changed.
