OK, I’ll accept I should have removed the old version to do a clean install. My excuse is I’ve just done a number of updates which were really smooth like chocolate experiences of updating into the existing folder over the existing version and the installer takes care of everything. Not even a reboot needed. K-Lite Codec Pack and Oracle Java are especially liquid like a fresh lager in this respect :slight_smile:

So I scraped out every remnant of 2261 and then rebooted and reinstalled and rebooted. So far, good.
