GEONExT

This is a silent installer and uninstaller for GEONExT (dynamic geometry software).

<package
                id="geonext"
                name="GeoNExT 1.71"
                revision="1"
                reboot="false"
                priority="1">
                <depends package-id="java6" />
                <check type="uninstall" condition="exists" path="GEONExT 1.71" />
                <install cmd='%SOFTWARE%\geonext_win171.exe /SP- /VERYSILENT /SUPPRESSMSGBOXES /NOCANCEL /NORESTART /MERGETASKS="!desktopicon"' />
                <upgrade cmd='%SOFTWARE%\geonext_win171.exe /SP- /VERYSILENT /SUPPRESSMSGBOXES /NOCANCEL /NORESTART /MERGETASKS="!desktopicon"' />
                <remove cmd='"%PROGRAMFILES%\GEONExT\unins000.exe" /VERYSILENT /SUPPRESSMSGBOXES /NORESTART' />
</package>

Note: Maybe the command line switches for the installer are a bit paranoid, '... /SP- /VERYSILENT /MERGETASKS="!desktopicon"' should be enough (delete the MERGETASKS switch if you actually want the desktop icon to be created).
