1. Personally, I would highly suggest you change your application so this
CustomAction is unnecessary. You are in for a world of pain in the long run.
<smile/>
2. The Registry element has been deprecated in WiX v3. The warning tells you
exactly what to do.

3. You'll have to condition your CustomAction in your first version of your
MSI to not run on upgrade in the cases you are trying to avoid. If you have
already shipped the first version of the MSI then you probably have to
release a patch to that version to add the condition. After the patch is
applied then you can try the upgrade.

4. See #1. <smile/>
