I feel pretty stupid asking this question, as there might be a simple solution ("go to IA's website and download and add the module") but is there a way to add the Perspective module to a gateway without going through the installer? I'm trying to avoid restarting the customer's gateway - if it can't be done, I'll have to schedule a time to do it but I would like to avoid that, obviously.
I've never run into this situation before as I have done 95% Perspective-only development.
