could be replaced with :
<upgrade cmd='cmd /c if exist "%PROGRAMFILES%\Mozilla Sunbird" rmdir /S /Q "%PROGRAMFILES%\Mozilla Sunbird"' />

>    <upgrade cmd='"%SOFTWARE%\sunbird\sunbird-0.5.en-US.win32.installer.exe" -ms' />
>    <upgrade cmd='cmd /c del /q "%ALLUSERSPROFILE%\Desktop\Mozilla Sunbird.lnk"' />

Alternatively you can use exit code :

<upgrade cmd='cmd /c rmdir /S /Q "%PROGRAMFILES%\Mozilla Sunbird"'>
 <exit code="0"/>
 <exit code="2"/>
</upgrade>
