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).
