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.
Next
install JMRI.
