I started installing VS and then my computer turned off suddenly (due to overheating).
When I was reinstalling it, an error message appeared saying:
Can't install in a non empty folder.
So I deleted the folder C:\Program Files (x86)\Microsoft Visual Studio\2017\community
Then, when I tried to install it, it failed.
This is the log:

Go to your folder C:\Program Files (x86)\Microsoft Visual Studio\2017\community
Make sure this folder is Empty. There shouldn't be any other directory inside, then check your error has been gone and Install button is enabled.
