Morning all. I did a fresh install of 10.11.6 last night on my MBP 3,1 which went well until I reinstalled Office using the last version for 10.11 as provided by MS on their downloads page. The apps install fine but when I try to sign in to my account for activation, instead of being asked for a password, I get a blank window. There's lots of reports of this behaviour on various forums but none of the work arounds work now. Thinking it was a duff "last version" problem I tried earlier versions including the version I originally used to install a couple of years ago but no luck. I've tried different Internet connections, dns servers and turned off 2FA but no joy. Has anyone else seen this problem or know how to fix?
