Browse to C:\Windows\Microsoft.NET\Framework\v2.0.50727\ and click the file that says “RegAsm.exe”. You will see a brief Windows DOS command flash on the screen. That’s how you know it was registered successfully. You only have to browse to that file the first time you do it.

You just need to select that option and it will register the file.
