looks like others have had this in the past … for me it's v9 (mac) — currently on Version 8.5.2 (Build 805.60133.100). Prompted to d/l and install v9, move through the prompts and it downloads … I click on install and relaunch and am immediately prompted to log in. Cycle repeats. Feels like install never starts. How to fix ???? (never had this before).
