Problem with installing

Hi, I tried to install the “Land design” and I receive an error message that I don’t have a license for Rhino. Even I have one…
Can you help me?

Hi, this message just means that your Rhino version is not up to date enough to run Lands Design.
For Rhino 5, SR6 or newer is required. For Rhino 6, SR11, I think, but this changes with every new Beta.
The better is just to install the latest Service Release. Right now, SR15 for Rhino 6. You can do it from this link:
