I have made an improved uninstaller for a project with a custom uninstaller script, but I notice that the uninstaller exe is not replaced during an update of existing installations. This means that the old sub-optimal uninstaller routine will still be used for those. Is there any way to force updating of the uninstaller? If I manually remove the exe before running the update the file is replaced, but I have so far been unsuccessful doing this as part of the script (I end up with the old exe or no uninstaller exe at all).
