Checking for a dependency

[AetherMaster 0]

Hello everyone, I have a script that while running, uses programs that depend on the .NET Framework 3.5. I have it installed on my computer, but I'd like to distribute the script, so I'd like it to be able to check whether or not the computer from which it's run has the Framework installed or not. Is this possible? If so, how would I go about doing it. Thanks.
