  • Launch an EC2 instance.
  • Configure the RDS Security Groups and/or VPC to allow SQL connections from the internal IP address of the EC2 application server. Add an inbound rule for the security group to allow MSSQL from EC2 instance's internal IP address.


  1. Select MS SQL for Database Type.
  2. Under Connection Type, select Basic. For DB Server, enter the endpoint address of the RDS instance. and DB Database respectively. For DB Database, enter the desired name e.g. "decisions".

  2. In the Encryption Keys window, the installer will detect any existing encryption keys on the connected database. A prior key and its data can be restored via the Restore Key File by entering its key value.

    For a fresh installation and if not wishing to restore any existing keys, select Next to continue. Even if keys are found, restoring is optional.

  3. In the File Storage window, specify where Decisions will store files such as logs, documents, etc for the server. Assuming the default installation location was not changed earlier via the Advanced Settings, the default file storage location is C:\Program Files\Decisions\FileStorage. 

    Confirm the location and then select Next once done.

  4. Review/correct any warnings in the System Requirements Check before clicking Next to proceed.

    Local PC installations may run into an OS warning, but this does not prevent a successful installation. Production environments need Windows Server OS
