HI Otis,
Sincere apologies for not getting back to you sooner. A whole month! Time flies when you having fun, or working hard...
I understand the feelings about signing installers. We have to go down the same route for some of our client apps.
What about publishing it via the Windows Store? I haven't had a deep dive yet but I read that it automatically signs installers for the store. I assume you would have a similar verification process as the EV certificate though.
That said, there's a solution of course: It's an nsis installer however, so you can unzip it with 7zip. Once unzipped, copy over what's unpacked except the $PLUGINSDIR to a folder of your choosing and run the installer from there. What you miss with that approach is the .llblgenproj extension assignment to the project files.
I will try this with the next update.
If 7zip is also a forbidden program by your organization, let us know, so we'll see if we can solve it in a different way.
I'm not sure, I actually haven't had a good look at the Microsoft Security/Defender baseline policy defaults properly.
Btw, will you be able to run the designer as it's also not signed? (Well, it has a strong name and is signed but that's also not enough nowadays)
It seems to run fine once installed.
