Hi, I'm a newbie and I need help for silent installation of OOo3.1. I've read about it in other threads, but I still can't do it. I download the .exe form internet, I decompress it in order to use the .msi installer (since all the codes I have found are for the .msi and not for the .exe), but I don't know how to use the parameters with RunOnceEx.cmd. I use: REG ADD %KEY%\001 /V 1 /D "%PP%\UTILITY\OPENOFFICE31\ start /wait msiexec /qn /norestart /i openofficeorg30.msi SELECT_WORD=1 SELECT_EXCEL=1 SELECT_POWERPOINT=1 ADDLOCAL=ALL REMOVE=gm_p_Math,gm_p_Impress,gm_p_Draw,gm_p_Base,gm_o_Quickstart,gm_o_Testtool but it doesn't work. If I launch it manually from the cd (after Win installation), it works. I've tried also writing the code in different ways or using a SFX or a CAB, but nothing works. Could someone tell me how to perform a silent install (with RunOnceEx or other methods)? By the way: which are the parameters for avoiding the wizard configuration (registration...) at the first start? I've found -nologo and -nowizard... (I can't remember it), but I don't know how to use them. Thanks.
