Downgrading on Windows

When moving from a newer version of Postbox to an older version of Postbox on Windows, make sure to uninstall the newer version of Postbox first (see http://support.postbox-inc.com/entries/86035-how-to-uninstall-postbox) before installing the older version of Postbox.


When downgrading to an older version of Postbox, you might find some of your Postbox add-ons getting disabled. Download the appropriate version of the add-on for the version of Postbox you are using from the Add-ons list at http://postbox-inc.com/extensions.
