.NET 4.0 Installation problems
Ok I want to explain my situation. I had .NET 4.5 framework installed on my computer but have applications built with Visual Studio .NET using 4.0 framework. I tried to install a 3rd party tool to use within my applications but it requires a 4.0 install. So, I got the .NET 4.0 install and now I am all messed up. I uninstalled 4.5 and installed 4.0 and now I cannot open Visual Studio. When I reboot I get error messages for TFS and another message from MOM.exe and it says I must have 4.5 installed so after not clicking yes I eventually did but to no avail. I am looking to get the .NET 4.0 framework installed so I can move forward. Does anyone have any tips or tricks to get this to work ?

The two check boxes I alluded to are for .NET Framework 3.5 and 4.5. Even so, .NET FX Verifier will show you .NET 4 is there as part. It does on my machine. So really if everything verifies properly, the application should work. Otherwise, yes, call the third party.

Download it to a useful spot on your computer .
Now first go to Programs and Features, Windows Features and uncheck both .NET versions. Shut down, start up, go back to Windows Features and check both .NET versions. Allow to complete. restart again.
Now run .NETFX Setup Verifier to verify and correct problems.
Restart again and see if the problem has been fixed.
