aenhancers

Is this possible? I need to run After Effects and then render a 3D animation in another program. It's not practical to do both at once, so I'd like to have After Effects render and then have it lauch my suspended 3D render file. I assume the order would be 1) AE renderings finish, 2) the script lauches 3D render file, 3) AE quits.

I'm no good with scripting. Can anyone help me out? Thanks.
