Plug-ins error

created a Plug-ins but when I install it in another Rhino 7 it doesn’t work, what’s wrong?

get no error messages.

How did you install it?

installed the rhp file, Tools/Plug-ins/install

have created the rhp file using Visual Studio 2022

The easiest way to install is to drag the RHP file onto rhino. What you could do is to start a debug session in visual studio by attaching to the running rhino program, then install the plug-in. Maybe an exception is thrown that is otherwise not visible in rhino, so try to debug with catch all exceptions enabled.
Also, do you have any dependencies, like other libraries, or other dll files that the plug-in needs? These need to be in the same directory as the plug-in.

thanks for the tip.
