SPROG DCC JRE Installation on Windows

You need the Java Runtime Environment (JRE) installed on your computer to run JMRI DecoderPro, the application software required to use your SPROG device.
Note: this is NOT the same as getting a Java update in a web browser such as Firefox or Internet Explorer.
To check if you have Java, you can open a "DOS" Window (Start Menu > Run..., type "cmd" and Click OK),
and in the DOS window type "java -version". You will see java version "1.8.0_211" or similar if java is correctly installed.

If you don't yet have Java installed, you can get the latest installers for personal use from Oracle by going to http://java.com/java/download/index.jsp.

You must run the Java installer for version 8 or 11 (or have previously loaded Java) before running the JMRI installer in the next step, or it will issue an error message and stop.

arrow Next install JMRI.
