I've installed the JRE 1.6 environment as described in an other topic without any problems Now I'm trying to install the PlatinGUI-Linux-710r4.jar I've downloaded from ftp.sap.com. I'm getting Welcome screen of the installer, click next and wait...... It seems nothing is happening, I don't see any disk activity or changes in free disk space. Any ideas? I've found a workaround regarding installation ([URL]http://wiki.ubuntuusers.de/Baustelle/SapGui[/URL]) I've created the sapgui.conf file containing installpath=INSTALLATIONSPFAD disableui=true and started the installation with java -jar PlatinGUI-Linux-710r4.jar -i sapgui.conf
