Why not cut out the middleman and have it generate the XML? Or let the LLM generate the MSI database directly, without WiX. (Good luck debugging!)

LOL! I was asking Gemini Wix questions. The answers were wrong! When I pointed that out I got apologies and more code that didn't work. As with most newbies, I finally trial and error'ed my way out. I want to know how the "experts" have figured out how to use Wix. What is it that I should know but don't about learning Wix?

I actually got a working WiX MSI only because of GPT helping make 90% of the installer. the rest were random stack exchange posts because the docs or guides I found to write the XML were way off, old, too new for wix3 or something else was absolutely missing.
