Hello. I'm currently about 2 hours away from splashdown of the NASSP Apollo 8 mission, and I'm already thinking ahead to the next flight, probably Apollo 9 or 10. I have Orbiter 2016 installed, and have been using Orbiter_ng.exe while running the Apollo 8 scenario. Once I'm finished I would like to install the Orbiter 2016 beta, which I understand will allow me to maneuver while docked with the LM better. Do I need to uninstall anything, or can all these Orbiters live separately in peace? I see I'll need to get the D3D9 beta, do I need to delete the D3D9 I'm currently using? Also, I'm currently using NASSP V8-0 version 1519, I see version 1616 was just released. I assume there are a lot of important tweaks in 1616 that I should take advantage of? Can I just unzip 1616 into Orbiter beta, or do I have to delete 1519? Thanks.
