Ok build the plugin with Zoo licence management, so my plugin has a CRhinoLicenseValidator
class ( dunno if this has to with the issue),
After installing the plugin ( tried both using the rhi installer then my own built install file built with Innosetup )
I get a error message from Rhino that says unable to load the plugin, no other info is available just that message.
I then go into the plugins and install from there and it works fine , clearly it asks for a licence code since its the first load.
So I think the license validation may have something to do with the failure .
