We modify a lot of things in the default 4.0 template to suit our needs (like changing the string from Repairing to Updating, etc). One of the things we used to do in 3.0 was edit the XML file to set the default MSI parameters to /QN (no user interface) rather than the default /QB (basic interface).
How do we do that now in v4.0 without having to keep adding -Parameters in every package we create?
