[Solved] Cannot build on any platform

I’ve tried building on PC, WebGL, and Android, and all I get is an audio ding. Unity does not compile anything. I get no errors, no empty files, nothing. I have been able to build all of the previous games in the course. I’m trying to build a PC app to the Documents directory. I’m using Unity 2017.0.1p4. Any suggestions as to what I might be doing wrong?

I had to completely uninstall and reinstall Unity. Apparently, the patch either messed me up or didn’t install properly. I’m now running Unity 2017.1.03f again, and all is well.
