Thanks for the response. I had not tried a custom action, but I did just now. Same problem, doesn't do anything. When I go through the logs the NEWERVERSIONDETECTED and OLDERVERSIONDETECTED properties are not getting set. Therefore the conditions are false and the custom action never runs. I know very little about WiX and MSIs in general, but in the past when I used a custom action I had 1 action for setting the property and a second action that actually used that property. Do I need to do something like that? It just seems that the upgrade stuff isn't getting "executed" currently.
