Windows Installation:

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

1. Click here to download the 64-bit Windows DBS4 installation package
2. Once the download is complete, simply run the DBS4setup.exe program to start the installation process.

• If using EDGE or IE, ensure you click Save and not Run/Open File.
• If using Chrome, the download will be displayed on the bottom left corner. You may be asked to Keep. Click on Keep to continue the download.
• If using Mozilla Firefox, click Save if needed, and the download will then show on the top right corner under a blue arrow.

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’.

Mac Installation:

1. Only Intel based Macs can run DBS4, not M1. 
2. Via Safari only, download and install Java, as DBS4 will not run if not installed-  (www.Java.com)
3. Click here to load the JNLP version
4. Read instructions below to start program. 

If you are prompted with a message that does not allow you to open dbs4-client.jnlp, please follow the steps below:

1. Launch dbs4-client.jnlp, so the computer is aware this is the last program you are trying to open.
2. Top left corner of your Mac, click on the Apple logo > System Preference > Security and Privacy> Under the General tab, you will see at the bottom dbs4-client.jnlp – Open anyways. Click on Open Anyways.
3. Program will launch, and you simply have to login.
