I am working with JNLP and I'm unable to launch Java Web Start. The issue is specific to my machine. I am able to launch it on other PC's without any issues.

When I launch the JNLP the Java Web Start splash screen appears for a few seconds then disappears. The Java Console is set to Show but does not appear. In Task Manager the javaws.exe and jp2launcher.exe appear while the splash screen is open then terminate.

My machine: Windows 7 Pro 64 Java 8 Update 60 (Have also tried Java 8 Update 51)

Thank you for any help!

Because the issue was specific to my user profile on Windows, the fix was to...

  1. Uninstall all versions of Java.
  2. Delete C:\Users\\AppData\LocalLow\Sun\Java
  3. Delete C:\Users\\AppData\Roaming\Sun\Java
  4. Reboot
  5. Reinstall Java JRE or JDK

We had same issue of launching JNLP and the J2PLauncher process would exit. It seems to happen only when opening a JNLP file from a network location. if we copy the JNLP file to our local drive and run then the application starts normally.
