Missing 'System.Runtime.InteropServices.GuiAttribute'

[wowrs1608]

Hi,

I am compiling an old code with VS 2022 for Inventor 2022. One PC has no problem, but another can't.

I got these two errors. I search my drives and can't find these DLLs.

What I can do? 

Regards,

Pete

Changed to build again .net 3.5 solved the problem.
