Hi, I know I'm late in the discussion, but I'm currently facing the same problem :
I almost finished creating a mod, but when I build it, it says "Cannot determine which pantry path to use". Looking on some forums, I saw that it was because of the Assets.
When I try to run Development Assets from steam, it says " invalid app configuration", and I can't launch the Assets Editor from the Development Tools toolbar neither...
Could you detail me how did you do to "fill it in the Modbuddy configurations" ?
Many thanks
