My c# com-interface using tools don't work with Photoshop 2021 anymore

Hi i use c# tools to communicate via the com-interface with photoshop.
To automate communication between photoshop and various tools (Substance Painter, Mari and Maya).

But they won’t work with PS 2021.
Is that suppose to still work ?

Am i doing something wrong in my code ?
I use reflection in my c# tools.
Type typ_ps = Type.GetTypeFromProgID(“Photoshop.Application”);
app = Activator.CreateInstance( typ_ps);
This is already where it errors out.

I noticed that the PhotoshopObjectLibrary has 2021 in the properties (in VisualStudio where i reference them) but the PhotoshopTypelibrary has still Photoshop 2020 in the properties showing.
I don’t know if it has something to do with it.

Any reply or hints to how make it work again would be great :slight_smile:

Thanks a lot and stay safe,

Found the problem.
Works now.
