I have seen a lot of emails with people mentioning that you cannot launch RSD from Intralink. Well, I just got it to work. I was actually visiting with an individual from PTC help and I told him that I got it to work. He was surprised, he said it had never been done before and he asked me how to do it. Anyway, in intralink, go to #Intralink, #Define ProE Commands, and create a new one called "RSD, in the command, place the directory of your batch file like the following example.
Hope it works for you. Let me know if you have any questions.
