I have not found a way to do it as the main executable and the uninstall wpkg is using is all using the identically named files for checks etc, so the uninstall of the lower or earlier version can inadvertently uninstall the newer or higher version as it does it's checks it finds the, now newer, exe is still present. 

Obviously the mistake and big error was to have multiple wpkg packages all referencing the same executables. (i.e. firefox.exe and uninstall.exe). We should have only ever had a single firefox pkg called firefox.

Does wpkg have something like this pkg supercedes or replaces this other package?

Thanks.
