Hi,
When PlugIn.GetLicense() returns true, the license is validated, which means the “seat” is in use.
If I want to free that seat again, I have to shutdown Rhino. But is there a way to do it without shutting down Rhino? PlugIn.ReturnLicense() seems like the right method (based on the description), but it always returns false, and the “seat” is still occupied.
LicenseUtils.LogoutOfCloudZoo() will return your cloud zoo license but it will also shut down Rhino. I don’t think we have anything in RhinoCommon that will keep Rhino running after logging out.
