Unfortunately that didn't work either. Guess I'll have to do it manually. On the bright side I am now more familiar with CKAN
Edit: Just figured out that if you check version 1.6 as well as 1.7 in "Compatible KSP Versions" everything works fine.
CKAN is showing AVP as incompatible with KSP 1.7.2 (and obviously 1.7.3). Any chance this will be updated soon or should I just roll back my KSP version to 1.7.1?
