I’m having problems registering my plug-in with Rhino 6. For Rhino 4 and 5, I simply added the plug-in name and filename to the registry (http://developer.rhino3d.com/guides/rhinocommon/registering-plugins-windows/). The next time Rhino started, the plug-in would fully load. Now in Rhino 6, I just get a message saying “Unable to load ExactFlat.rhp plug-in: initialization failed.”.
But, if I install the plug-in through Options -> Plug-Ins -> Install button, the plug-in installs without any errors.
Do I need to do something more in addition to adding the registry keys according to the registering plug-ins guide?
