Could not resolve an instance of Umbraco.Core.Security.BackOfficeUserManager from the Microsoft.Owin.IOwinContext GetUserManager method
Detail in the log is

Anyone know what is causing this and how to resolve? FYI I am installing the site from the zip version.
Anyway seems the error hasn't prevented anything from installing and it's the final automatic login that is not working so I'll still be able to work on the site.
Yeah, a little look around the code on github suggests that this step is just there to redirect the user to the back office. A refresh should help Umbraco correct itself.

I just had the same with a clean installation from a Nuget package. But only using Chrome. Not sure why, but installing from Firefox worked for me.
Same error here, installing from Nuget. Also in Firefox
Found an issue on YouTrack that relates to this. It says version 7.3.3 but I can't find any mention of that version so wonder whether they mean 7.3.2.
