It's a PT-BR CD, so it's "INSTALAR.EXE". I downloaded this CD many years ago... And work perfectly. I think the log doesn't show anything... 2008-02-23 19:39:49 : Logging started. 2008-02-23 19:39:49 : - 2008-02-23 19:46:02 : Setup File Description: Carregador da Instalação Microsoft 2008-02-23 19:46:02 : Location of Setup.exe: D:\Office 2003\INSTALAR.EXE 2008-02-23 19:50:12 : Logging started. 2008-02-23 19:50:12 : - BTW, after the error that I mentioned before, the Slipstreamer crash. The autorun.inf file (I didn't touch it): [autorun] OPEN=INSTALAR.EXE /AUTORUN ICON=INSTALAR.EXE,1 shell\configure=&Configurar... shell\configure\command=INSTALAR.EXE shell\install=&Instalar... shell\install\command=INSTALAR.EXE Should I rename "INSTALAR.EXE" to "SETUP.EXE" and then try to use the Slipstreamer in English language? Because the software is not fully translated to Brazilian Portuguese.
