→General info
If you have a lower version of Thunderbird installed, it will be automatically removed before Mozilla Thunderbird 1.5 installs.
As the Thunderbird install now nicely upgrades and doesnt leave the old one into in the registry, there is no need to differentiate versions in package id.
When a new version comes out, just replace the installer in "upgrade cmd" with a new one, and then increment the package revision number - this puts the upgrade command to work.
<remove cmd='"%PROGRAMFILES%\Mozilla Thunderbird\uninstall\uninstall.exe" -ms' />
</package>
