This is probably because your CA is scheduled as immediate, rather than deferred. You need to set Execute=deferred, and Impersonate=no on your CustomAction element.
However, this presents a problem - deferred CAs do not get access to properties. Instead, you need to use the CustomActionData special property. You set a property with the same name as your action (in this case, SetEfxZlibLibraryAction) to the data that you want to make available to the custom action. The DTF method (session.CustomActionData) for this in C# has some special parsing rules which can be used to pass in multiple elements of data.
