I'm using ArcGIS 10.2 on Windows 8.1. I started working on a project on one of my schools computers and when I loaded it back onto my personal laptop the tab for the search window had disappeared. Trying to launch it from the tool bar or the windows menu doesn't work either. Everything else seems to be working as it should be and the search option is still working in ArcCatolog. I've tried a few of the fixes suggested elsewhere on the forums but they haven't worked. I'm not sure what to do short of reinstalling but I since I'm using a student evaluation version I would prefer to avoid that.
