As you don’t seem to get a formal answer …  
See different other postings with P21 answer like:  
“_Pinnacle 21 does not support older versions of applications to ensure correct functionality of the validator and to meet regulatory agency requirements._”

Question back to all users: as updates are done automatically and without notice, how do you validate after such an automated update? Start over all again?
