Hi, i am relatively new to Wix. I created a Setup where we can define a connection string on the first install. Now i wanted to upgrade, and have the possibility to skip some Dialogs that are only used in the first install (like the one that asks for the server and database), and i didn't want to remove some XML files that were configured in the first install. For what i have read, a major upgrade removes the previous installation, and replaces all the files. How can i get a condition that says if its first isntall or upgrade, to just install some components, skip some dialogs, not reconfigure XML Files (i'm using util:XmlFile) and not remove some files?
Thanks
