What should I do that Panoweaver fails to launch?

Please check the JRE first. make sure that you have installed JRE (Java Runtime Environment) 1.6 or later version. Please go to the installation directory of Panoweaver , and delete the file "settings.dat" in the folder. Then restart the computer to have a try. If it still doesn't work, please uninstall the JRE and remove it completely from the computer, and then reinstall it to have a try.
