Python script plugin : menu item

Hi,

I have created a python plugin which is installed with my app (a renderer). Currently, I install the python files in a library folder of IronPython. I also install a RUI toolbar in the Rhino Plugins install folder, then I add this RUI to the active toolbars in the registry.

The plugin command is accessible for every user, since it is installed in the main Rhino folder. However, the toolbar cannot be installed to HKEY_LOCAL_MACHINE (it does nothing) but only to HKEY_CURRENT_USER. This means the toolbar is added only to the user who installed the plugin.

Is there another way to add a menu item along with installing a plugin? Maybe programatically, but I do not think python scripts can execute automatically at startup?

Thanks
