Repairing broken Visual Studio .Net install

I’m in the process of learning C#,but I ran into a small problem installing VS.Net: when I tried to install the prerequisites, it would launch the setup for my Intel Chipset, and then quit, without progressing to step 2 in the overall VS.Net install. I found the solution here (scroll down to last post).

The solution is to launch regedit, find this key :

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App

Paths\setup.exe\(Default)

and delete it. Mine was (unsurprisingly) set to the Intel Chipset installer, and VS needs this to be blank.
