Operating Systems Remarks Windows The EU-Seased and Euroseismic GIS applications have been tested under standard configurated Windows versions. Under Windows 98, ME and 2000 in combination with Internet Explorer 5.0, 5.5 and 6.0 the application should run without problems. Windows XP (in combination with IE 6.0) users might have difficulties viewing the GIS application due to the fact that Java VM (Virtual Machine) is not installed. You can check this in Tools > Internet Options > Advanced (under Java). In this case please download Java VM from the Sun website: http://java.sun.com/j2se/downloads.html and then install. Apple Macintosh Apple Macintosh users need to use Internet Explorer 5.0 or higher.
