Visual Studio 2017 Crashes when opening any Project. "CLR20r3" "devenv.exe"

[Jay Mccrum]

I installed Visual Studio 2017 via Unity.

I'm trying to open an old project.

Visual studio starts up and launches fine.

When you create a brand new solution, Visual Studio 2017 crashes.

When you open any solution, Visual Studio 2017 crashes.

I am currently on Windows 7.
