Set this up one time, after it is associated it will not be necessary to do it again.
Use File Explorer and locate the NEWLY downloaded file jviewer.jnpl jviewer (x).jnpl. If you execute an older version you will get an error "Invalid Session Token. Authentication failure." later.
Associate the file (properties > Open with ...) to "Java(TM) Web Start Launcher" or "Chose another app" and find javaws.exe at C:\Program Files\Java\jre1.8.0_351\bin.
If the association of .jnpl and Java is happy, you will get this and are on the right track:
After Java is installed and .jnpl is associated to Java the sequence is simpler to launch the console.
Click Remote Control Launch at Dashboard > Save > Retry > Open Folder. This opens File Explorer to the Download folder, the latest jviewer (x).jnpl should already be selected. Double click it and Java start and the console should open.
