Answer 1

I am not sure if your issue is sorted or not, I just faced the same issue even though i have created a few of these msi files with Wix.

In my case, it wasn't finding the "HeatedComponents" that I am generating automatically within the project. I had to load this file into the project, (these files or folders may be inside your project folder but in most cases VS does not load them automatically).

You have to Right Click on the project -> Add -> Existing Item; and select the file/item that is required.
