Installs ok on 8.27 here. What message do you get when you click the Details button in your screenshot?

This is the link to the plugin page

Your best bet is probably to contact the plugin author via the support email link found there.

In the meantime, consider what might be pertinent differences between your system and your friend’s. For example are you both running Rhino with Netcore (the default in 8) or have you changed to Net Framework for compatibility with some other plugin? Do you have the same language settings in Windows?

I send the plugin author an email, hope it will be fixed soon , and probably not i have some plugins that he doesn’t have
