Thanks for the suggestions, I really appreciate your help. I am already remote debugging with Wing, though I could never get a connection on the server.
I spent a couple hours yesterday setting up my local machine to replicate the environment on the server. It turns out that because the Windows Service isn't run as a regular user with regular permissions, maya standalone won't launch. On my local machine, the service pops up a warning (from the maya instance) that a valid MAYA_APP_DIR can be found. I assume that because I was using a remote desktop connection to the server, I never sawt the pop-up, and the process wasn't really hanging, just waiting for user input. Now I just need to figure out how to give maya a valid MAYA_APP_DIR under a service, which doesn't have the same user/system permissions that a regular user login gives. -Ian On Sep 22, 11:48 am, Paul Molodowitch <[email protected]> wrote: > Hey there - first of all, I'm sorry I didn't notice your earlier issue.
