Using an External MSSQL Server during Install
During install when using a database version not supported the error reported by the installer is that it can't connect to database. It leads to a troubleshooting that MSSQL has the correct username/password and certain features installed. When looking at the setup logs the error is being trapped that X version of MSSQL is supported. If the error being trapped in a log was displayed back in the installer would assist in troubleshooting and documentation during installs.
