I traded my Perpetual License to a Subscription License.  I got OpticStudio now running under the new Perpetual License, so I would think that I have to “return” my old Perpetual License.  How do I do this?  Just send it away through the License Manager, or something else?

Hello Joel! 

Yes, please transfer your old license L115670 via the “send license” tab in Zemax license manager. When it asks for an email address, use sales@zemax.com

Thanks!
