DBS4 Installation Instructions


We are happy to announce the latest release of our flagship program, DBS4.

With this release, we are also announcing the decommissioning of all past desktop services, including DBS3. This process will happen in two stages, first with our Express Odds service, followed by our Premium Odds Service. The deadline dates for upgrading are:

Express Odds: September 14, 2018
Premium Odds: October 4, 2018
(We encourage all users to upgrade as soon as possible to ensure smooth transition to the new version.)

Window Installation: We have simplified the DBS4 Windows installation process, packaging all of the required programs into a single program for 64-bit Windows:

Mac Installation: Mac users can continue to use our standard JNLP DBS4 installation process:

  1. Download Java (www.Java.com)
  2. Click here to load the JNLP version

Use the link below to test out the DMG Mac version which does not require you to install Java:

After installation is complete, use the DBS4 icon on your desktop or start menu to launch the program. To add the DBS4 icon to your taskbar, right-click the icon and select ‘Pin to Taskbar’.

For those customers who use a firewall, please make sure to whitelist the IP range The default port used by DBS4 is 4451. To switch to using port 1111, go to Login Setup on the Login window, select port 1111, and click the OK button.

The functionality and features of DBS4 are very similar to our past products, so users will be able to setup their screens to closely match the DBS3 setup.

Our goal is to deliver the most complete and easy to use program to all customers and your feedback is key to this. We encourage all questions and feedback, big or small, and our friendly Customer Service team is ready to help:
