I am trying to install DNN 9.1.1 on Windows 10 machine, running SQL Server Developer 2012. The Platform Installer won't even recognize that I have SQL Server installed. When I do a manual deploy, the SQL Script Installation keeps failing with a huge exception that starts with:

":04 Minutes | 18% ERROR occured - System.Data.SqlClient.SqlException (0x80131904): Invalid column name 'TabId'. Invalid column name 'TabId'. at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection, Action`1 wrapCloseInAction) at ..."

I have installed DNN 7 before on this very same machine. Whats the issue and/or workaround?
