[wix-users] WiX Bundle Upgrade Issue

[Edwin Castro]

I don't expect the bundle to remove your current MSI. I expect your
MSI is removing the older version. If you're using major upgrades,
then use the UPGRADINGPRODUCTCODE property to help determine if you're
getting uninstalled for an upgrade.

You can condition custom actions that are sequenced after
InstallValidate to handle major upgrades by using the
UPGRADINGPRODUCTCODE property:

If you want a custom action to run during an uninstallation of the
product, but not during the removal of the product by a major upgrade,
use this condition.

REMOVE="ALL" AND NOT UPGRADINGPRODUCTCODE

If you want a custom action to run only during a major upgrade, use
this condition.

UPGRADINGPRODUCTCODE

Note that the cached MSI for the old version performs the uninstall
which means it must already have the clean-up custom action with an
appropriate condition. If you have already released, then you'll need
to patch that MSI out on the field before it will do the right thing.
