[wix-users] How WixTools manage the upgrades?

[Markus Kramer]

Edwin,
In an Major Upgrade, how do you specify the condition for a Custom Action
that shall only execute in an upgrade?

I tried
*     Installed AND NOT REMOVE*
but in a Major Upgrade, the Custom Action was skipped (Condition not met).

Also, how do you schedule  RemoveExistingProducts early?

Best Regards,
Markus
