What is the best way to prevent an installation from running if a related product has not been installed? If product A has not been installed I want to prevent product B from installing with a message to the user that they're running them out of order.
Hi, You can do a System search for a component guid or product guid for Product A.
If it finds a guid in the registry , you can then insert a custom action to run only if the GUID is detected. The custom action warns the users, and then exits the installatino.
