I am stuck at the 'We're getting things ready' for over 24 hours when I am trying to add an account to my outlook. Is this normal?
Same thing is happening to me! I'm determined to fix this since there is NO help given elsewhere for this issue.
I've also tried the Offline installer but still didn't work for me, gave the same "We're getting things ready" for hours to no end.
Then I tried the Support and Recovery Assistant for Office 365 tool to install Office 2016 and it worked! Unfortunately the tool itself requires Internet connection to prepare, then it will still use Internet connection to install Office (so my offline installer was worthless).
But to me this tool was worth it.
Using the tool, the "We're getting things ready" shows only for less than a minute, then immediately changes to installing... (which takes a long while, but at least there's a progress bar with visible movement).
