Not resolved, never got the ISY launcher icon on the desktop, so I'm just running start.jnlp every time.

Nope still get the error.

Java Console:

Missing Application-Name manifest attribute for: https://isy.universal-devices.com/launcher/isyfinder-2.0.jar
java.io.FileNotFoundException: C:\Users\dikha\AppData\Local\Temp\udi_launcher.state (The system cannot find the file specified)

Not a new user, just setting up again.  I have deleted Java, reinstalled the latest version, followed the link to get start.jnlp, ran it, and got the ISY Launcher shortcut.  But when I run it I still get the "cannot determine a valid java home" error.  I'm on the latest release of windows10.  I can use the Administrative console from the finder, but the only way I can get the finder is by running start,jnlp again.

Attached is the Java Console contents.
