I am doing a new install on a Windows 2012 R2 server trying to install SIM 7.6 to a Cluster of SQL servers, thus creating the DB once the installation is complete. I have tried setting the instance name for the host and instance, the instance\instance for the host name, and instance in instance, left the instance blank, port is 1433.
The service account that I created has every right known to SQL and SQL Stuide/Manager is set up correctly.
