I did attempt this. The result was consistent CTD on load. I am downloading 1.41 and installing on windows. My KPS is 1.42, if compatibility is broken already.
I have been able to include some functionality from Principia by messing around with the file organization, but I have not managed to make it work as advertised. At best, I can have axis tilt.
I read that the process is more involved on some other forum post. Perhaps their intent was that we may not simply check a box in CKAN. I am indeed, however, finding it to be more involved.
