After finishing the installation configurations and starting the install, it fails almost immediately with an error similar to:
Failed to connect to database. Error Message: CreateProcess: sqlplus -L <username>/<password>@'(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=<host name/IP>)(port=<port>))(CONNECT_DATA=(SID=<sid name>)))' @"<path to install temp folder>\justExit2134.sql" error=2
Clicking 'OK' exits the installer.
