Found the trick for RealPlayer One v2 through try & error "RealOnePlayerV2GOLD_de.exe -s" ATTENTION: Parameter is case-sensitive!!!! NAV2004: start /wait NAVSETUP.EXE /QB pskill CfgWiz On my German Version i don't need any activation, but it still asks for Registration and some other setup things like liveupdate and planning scans. Just try it. I spend hours to find a registry trick but no way Found also a way to integrate Updates and "Re-Abo" TightVNC: Install it, configure it, export Registry settings for TightVNC to for example "settings.reg" repack the files and make your own installer with things like SFX-Factory or WinRAR (my favourite because of compression). When creating links you can use the following: winvnc.exe -settings (config menu) winvnc.exe -install (install server as service) winvnc.exe -remove (uninstall service) winvnc.exe (just starts normal server) vncviewer.exe (starts viewer) vncviewer.exe -listen (launches viewer in tray) greets
