Issues writing my first addin

[mgrenier1]

Inventor recognizes it and it gets listed in the addin manager but it just won't load it.

I'm trying to get some Inventor VBA projects besides the Default.ivb one to load automagically whenever I open Inventor.

I zipped my entire vs studio project

Also, is there a way to generate the .addin file automatically? I had to create it manually, by typing on my keyboard like a monkey in 2025. Maybe I setup VS Studio wrong or something, I wouldn't be surprised. I just can't seem to find some up to date info on creating addins, all the tutorials I find are still building it using .NET Framework 4.x

I’ve been there  Inventor addins can be super picky. If it’s showing up in the Add-In Manager but not loading, it’s usually either registry entries, load behavior settings, or mismatched .NET version.

About the .addin file — yeah, you can generate it automatically using Visual Studio templates for Inventor addins, but a lot of docs are old. Make sure your project targets the .NET version Inventor expects (usually 4.8 or whatever your Inventor version requires) and that your addin’s LoadBehavior is set to 3 for “Load on Startup.”
