Deploying a custom Solidworks Addin

This is not the first time this question has been asked. I have written a custom addin and now need to deploy a set up project to deploy the addin on 4 machines. I COULD do this manually but would rather use a set up installer.

I have Advanced Installer (purchased after failing using WIX) that I purchased to do some desktop apps. So far my attempts at installing my AddIn has failed. I have tried both Advanced Installer and the installer template that comes as a add in for Visual Studio 2019.

The docs at Solidworks is terrible. There is nothing there at all about registering the dll's which I understand is necessary.

Could anybody please guide me as to the necessary elements needed to create a installer package for a SolidWorks custom AddIn?
