  1. Download the current build from the North American server.
  2. Unzip the build to the desktop of the workstation. The setup icon displays.

Post install steps for new workstation installations

  1. Once the install is completed, copy your group's Relais.ini file into your destination folder.
    •  A link to download the Relais.ini will be provided to you via an email.
  2. Run CreateODBC.exe (found in your group's destination folder).
    • This utility reads the Relais.ini and uses the database settings to create an ODBC connection to the Relais database
    • Ensure you have copied in your Relais.ini prior to running Create ODBC.exe

If you use the default Windows “SQL Server” driver  to create the windows ODBC connection after installing 2016.x,  ensure that the “UseEncryption” option is set to N in your Relais.ini.

If you wish to enable the encryption of the database connection you must select a Native SQL server driver from the list of potential drivers when running the CreateODBC application. More information can be found on the Relais 2016.x install and upgrade page.

Install/update all remaining workstations

Repeat Downloading and unzipping Relais 2016.x through Post install steps for new workstation installations for each workstation depending on if you are upgrading or installing a new workstation.  Select Relais D2D from the product list.
