Cannot open Visual Studio - throw error 'cannot run when setup is in progress'

Question

I am trying to open Visual Studio, but it is giving an error:

cannot run when set up is in progress

It was running fine before when I restarted my machine. I have already installed this version from past one year.

Answer 1

Try to check Task Manager and kill any process related to Visual Studio (any version).

Update:
as many people mentioned in the comments it could be better to wait a while until those processes end themselves
