This helps somewhat. I can detect the final uninstall using the following
test:
(?ProductComponent = 3) AND ($ProductComponent = 2)
But I can not detect the first install of the component. The following
test fires for both the first and second install for some reason:
(?ProductComponent = 2) AND ($ProductComponent = 3)
So why would (?ProductComponent = 2) yield true during the second install?
Could this be a timing issue? (In my sequence, the test is
After='InstallFinalize'.)
These tests were done using WIX 2.0.4221. I built one merge module
(including my component and the custom action) and two MSIs that
incorporate it.
Thanks!
