Finally I got the newest Quickr version to work together with the newest Domino version.
Before the last version update, I was running Quickr 8.2.0.0 and Domino 8.5.1 and it crashed almost daily.
Domino left a 0 byte NSD file behind each time it crashed.

Now it hasn't crashed once yet.
All SNAPPS apps are also installed and working fine.
