Just go to the last post for the most current build.
>>There are some issues in Orbiter 2016
Would you happen to know what some of these might be? I have been using it for several months without issue. It is quite complex, though, and it would be nice to know if the beta makes anything 'easier'.
There is no working Apollo for Orbiter 2016.
You have 2 options: Download Orbiter Beta with NASSP 8, or download Orbiter 2010 with AMSO.
I used Orbiter Beta with NASSP 8.0 but crashed!
