I recently had a problem where my installed Visual Studio IDE just wouldn’t launch. Sometimes the startup screen would show up for an instant and then go away. Rebooting my PC didn’t help either.

To solve it, I ran the Command prompt with Admin privileges and typed in the following. Running either one of these or both will likely solve the problem. I had to run both in the same sequence as given below to solve the problem:

C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE>devenv.exe /ResetSettings

C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE>devenv.exe /Setup
