[wix-users] How to conditionally remove configuration?

[Markus Kramer]

Greetings,
I use custom actions to remove configuration on uninstall, depending on an
property (REMOVE_CONFIG)

I would like to replace my custom actions with RemoveFolderEx but
RemoveFolderEx is called so early, that there are no properties yet.

How could you make  RemoveFolderEx depend on a user property?
E.g. could I call  RemoveFolderEx from my custom action?

Can  RemoveFolder (without Ex)  depend on a user property?

Is there a best practice for configuration data?


Thank you,
Markus

P.S. I tried to search the mail archive but was unable to use the
