Desktop/Java Application

Hi LoadTesters

Im using HP Loadrunner 12, and I am pretty new at it. Actually I'm learning it using a downloaded tutorial.

In the tutorial they only show how to test web based applications. I'd like to know how to test Desktop/Java/win applications, which protocol(s) to use.

I have tried protocol advisor, but when I select the "Windows Application" in the "Record", the "Application" downdown is emptied, and the "Start Recording" button is dissabled. (see attached image).

NB: whenever I start typing in the "Application" dropdown, I get red text (error).

Please help. I am a begginer. 

Thanks a lot
