I located the insteon.jar file on the Universal Devices web site and I can extract it after downloading. But in which folder of my desktop should it reside or is supposed to download and extract whenever I attempt to log onto the ISY by using http://www.universal-devices.com/991/? By the way, the ISY is functioning fine and is running the current program. But I cannot log onto it to control my programs and devices so I need help in resolving what appears to be a Java related issue with the insteon.jar file.
