Re: [WiX-users] CustomAction on Uninstall but not upgrade

[cge <el...@av...>]

Yes, I can see in my log where UPGRADINGPRODUCTCODE and UPGRADEFOUND are
being set to the appropriate GUIDs. What I don't understand is how I can
prevent my CustomAction from being executed when the old outgoing product is
being uninstalled. I only want my CustomAction to execute when an uninstall
is run directly, not when it is run as part of an upgrade.

Is there a set of conditions that match that scenario?
