Oh.  I thought you were referencing the original code.  So, no, I did not add the red stuff.

Did you add the two pieces of code marked red?

It requires that ".dll.config" if you use the Newtonsoft JSON (it overrides some old versions there).
At least that's my assumption.

Regarding certificates - yes, it's a really cool business model. They validate your pass basically, yes.
BTW Microsoft itself does not hesitate to charge for that $540 a year (via DigiCert)

Yes, this was one problem, Webview2 and Newtonsoft.Json.
But also "VisioAddin.dll.config" is required and I do not understand why.
This is a xml document that contains default values for the settings (defined in project properties).
I could simply add it to Product.wxs and it should work.
But in a similar project this is not required and I would like to understand what happened here before I do that.
Do you have an idea?

So far I only have a few users, all of whom I know personally.
So I can show them how to bypass the security mechanisms to install my SW...
But of course that is not an option for a reputable company.
250€ a year only to verify a copy of my ID card (or however that works) is a bold business model.

Wow!  It is a feature!!!  Since I only use English, I cannot indulge in such benefits.     Poor me.

How did you do this?  I tried and it made no difference,

The error is most probably you need to include the dependency DLLs (Microsoft.Web.WebView2) explicitly to the setup (Product.wxs), it is not automatic
      <Component>
        <File Name="Microsoft.Web.WebView2.Core.dll"></File>
      </Component>
      <Component>
        <File Name="Microsoft.Web.WebView2.WinForms.dll"></File>
      </Component>

Without certificate, the issue is, most probably the BROWSER will block download of the EXE/MSI (smart screen), so users won't be able to even download it
Signing with identity card is a dream, I doubt it will ever happen - these stupid certificates is a big business...

Visio 2019 Professional (16.0.10409.20028)

Which Visio version do you use?

Edit:
Ok, I can reproduce that it does not work.
I will check that later.
Until then, build the add-in yourself, please.
