What's the most straightforward method for testing for installation of the correct version of the .NET framework?

I have an app I'm working on that requires the 2.x framework. If it's not installed , I'd like the program to gracefully and silently exit rather than popping up the error box.

It would be nice if it could also notify me of the error -- perhaps exiting with a unique errorlevel that I could test for in the script that will run the app.

Thanks!

Thanks for that information, however those articles apply to application deployment and specifically state that they do not address how to make the determination programmatically (which is what I need).

In the first article it is revealed to use that that the version of .NET is stored in the Windows Registry. As we continue reading through the article we see:

The Registry Key for the .NET Framework 1.0:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramewor k\policy\v1.0
The Registry Key for the .NET Framework 1.1:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramewor k\policy\v1.1
The Registry Key for the .NET Framework 2.0:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramewor k\policy\v2.0

Now we can now build a routine to check the registry keys using the Microsoft.Win32 namespace.
