Your .jar file-association has probably been hijacked, perhaps by Internet Explorer.

You can fix the problem with:

  • Download and run the free Jarfix, or
  • Uninstalling an then re-installing Java Runtime, or
  • In Windows Explorer, right-click on the .jar file, select Open with and click on Choose another app. Navigate to and select javaw.exe. You would need to ensure a -jar parameter is added.

It would be better to add the JRE executable folder to the PATH environment variable, although not absolutely required.
