Rhino 6 updated from Rhino 5

Hello.
I wonder if it is possible to install the new version of Rhino 6 with Rhino 5 official license?
Or do we need to bought a complete new software and it`s official license?

best regards

Not without paying an upgrade, no. You can install the eval version of 6.0 and use it for 90 days though.

You can buy an upgrade, you do not need to buy a full version if you already have a paid license of V5.

That depends on where you are in the world but here is a start:

Then the Euro prices should apply, check with your preferred reseller in your area.
