This is a silent installer and uninstaller for Opera'''8'''.

On For Opera '''9'''.x /s seems to bee not enough. You had to add /v/qn Upgrade from Opera 8.x worked well.6:

<package id="opera" name="Opera 9.026" revision="902960" reboot="false" priority="11000"> <check type="file" condition="versionequalto" path="%PROGRAMFILES%\Opera\Opera.exe" value="9.260.858510447.0" /> <install cmd='"%SOFTWARE%\opera\Opera_9.02_Eng_SetupOpera_960_int_Setup.exe" /S /vV"/qnpassive /quiet CREATE_DESKTOP_ICON=1 CREATE_QUICKLAUNCH_ICON=0 CREATE_STARTMENU_ICONS=1 MULTI_USER_SETTING=1 INSTALLER_LANGUAGE=en"' /> <upgrade cmd='"%SOFTWARE%\opera\Opera_9.02_Eng_SetupOpera_960_int_Setup.exe" /S /vV"/qnpassive /quiet CREATE_DESKTOP_ICON=1 CREATE_QUICKLAUNCH_ICON=0 CREATE_STARTMENU_ICONS=1 MULTI_USER_SETTING=1 INSTALLER_LANGUAGE=en"' /> <!-- FIXME <remove cmd='"%PROGRAMFILES%\opera\uninst\opUninst.exe %PROGRAMFILES%\opera\uninst\install.log???' /> -->

You can also unpack the installer (i.e. with 7-Zip) and install the MSI directly.'''(no luck with this with 9.6)'''
