I apologize if this is answered elsewhere. So far (thanks to a post from Rob Mensching), my code will detect .NET 4.0 if it's installed and it'll pass right over it. I'm not able to correctly detect Microsoft Visual C++ 2010 x86 Redistributable OR Microsoft SQL Server Compact 3.5 Service Pack 2.
My code is below. I'm learning, so I would appreciate as much constructive criticism as possible.
