ok, here's some more fwiw
i had not experienced any of the issues reported by others
i just got a windows update, with KBs 2565063 and 3206632
i think ah ok here we go
let it do its thing
do an extra restart for good measure
opened test projects in sonar and another host
i still don't have any crashing with sonar or the ca2a (both latest versions, the ca2a is the from the recent freebie but vst3 only, sonar is the steam edition, and i'm assuming the shared components are the same for all versions, pim & vst scanner)
win10 pro x64, 8g, asio4all(!), nothing special, always online, etc
hth
