I had gotten a virus on my other computer so i went to my new computer, but now when doom builder 2 installs it says "You need the Role Management Tool for .NET Framework SP1!" And wont let me finish. I had it fine on my other pc but now...it does not work. and what is this role management tool i need for it?

It means you need the Role Management Tool for .NET Framework SP1.

It should be included in the latest update of your Windows operating system, unless you're using Windows 98 or something older.

At any rate, try clicking that link and seeing if it fixes what you need.
