Currently have Rhino 7 but company I work with have a very complex Grasshopper setup that uses Rhino 6, Rhino 7 doesn’t seem to work with it, so we need to purchase another copy of Rhino 6.
Hi Anousca -
If you bought a new version of Rhino 7, you can retrieve a legacy license key for Rhino 6.
The requirements and form to do so are on the following page: Rhino - Access Rhino 6

Thank you appreciate your reply 
Sorry Just a thought will this impact my Rhino 7 on another computer (not used at the same time)?
Hi - upgrades, and, in this case, “downgrades” are one and the same license. One being Rhino 6 will not work differently from having two Rhino 7s installed on two machines and using the same license. Make sure to float your license on the Cloud Zoo, and you should be fine.

Don’t forget that the free V6 offer applies only to full V7 licenses, not upgrades. This might matter if your V7 licenses were upgrades over V5 for example…
