@sschwa3 I found some old notes from when I installed the software - with Everleap I was able to skip some of the required steps.
(following instructions here - http://forum.greatreadingadventure.com/t/installation-instructions/30)
download/unzip/ftp to /wwwroot
Create new database with Everleap
with SQL SMS run New Query with Everleap instructions to create contained DB users
With SQL SMS create logins & users - Not in security area directly, but in Databases/[Database]/Security. Settings are slightly different - user type (SQL user with Password)/name/default schema/mapping not necessary it's already in there
Grant Execute Permissions
Cannot use IIS Manager with Everleap - all settings are already ok.
