4.1.3: Licensing

How do I know if my license has been installed correctly?

Place the Karamba3D "License"-component on the grasshopper canvas and connect it to a Panel component. The Panel should read out the details of the License.

Upon successful installation of the license you should be able to open example files which have more than 20 beam elements or 50 shell elements. Double check if the license and correct Karamba3D version are installed by opening the below definition:

22KB

License test.gh

Open

I have installed the license successfully, but when I open Grasshopper, it tells me "The maximum number of beam elements in the trial-version of Karamba3D is 20." How can I activate my license?

Each time you open Rhino, you need to make sure retrieve the license from the cloud or network server using "karamba3dgetlicense". If you have grasshopper open, simply place the -License component in your canvas then recompute the script.

I receive a message "Could not get a license" when trying to activate my cloud license.

This error when there is a conflict with an old license on your machine. Simply navigate to the License folder of your Karamba3D installation folder: typically "C:\Program Files\Rhino 7\Plug-ins\Karamba" or "%USERPROFILE%\AppData\Roaming\McNeel\Rhinoceros\packages\7.0".

Find the "license.lic" file and delete it.

Restart Rhino and run "Karamba3DGetLicense" to activate your license.

I want to switch the cloud license to another account

This can be simply done by logging into your Rhino3D Account. Navigate to your installed license (most likely found in "Personal Licenses"). Click on the Karamba3D license. Then you can simply click "Remove from Cloud Zoo"

Now you can add your license to a new Rhino3D account using the same license key your received.

I can't seem to delete a license from the Zoo Adminstrator

At times when a license is in use, or invalid, then the license cannot be removed from the Zoo Administrator. A pop up appears saying that "The License XXXX could not be deleted because it is in use."

• If the license is in use, then select that specific license instance, go to Edit > Recover. The license should be then marked as available and you can hopefully delete it.

• If the license still cannot be removed, then you will need to delete it manually in Windows Explorer.

  1. Go to %allusersprofile%\McNeel\Zoo or C:\ProgramData\McNeel\Zoo and navigate to your subsequent Zoo version.

  2. In the Licenses folder, there are various *.cluster files. These are the licenses in your Zoo Administrator.

  3. To check which *.cluster file refers to the Karamba3D license, simply check the creation date of the cluster file with the date the license was added in your Zoo Administrator by double clicking on it.

  4. Stop the Zoo Administrator. Delete those *.cluster file and restart the Zoo Administrator.

  5. All Karamba3D licenses should be now removed and you can now add the new licenses.

Can I run Karamba3D with the Zoo Network Server if Rhino is not running with the Server?

Karamba3D does not require Rhino to be running with a Zoo License for it to run on the Zoo Server. However if Rhino is running on the Network Server, then Karamba3D needs to run from the same license server.

Can I run Karamba3D with Zoo Cloud if Rhino is not running with the Cloud ?

Karamba3D does not require Rhino to be running with a Zoo Cloud License for it to run on the Cloud. However if Rhino is running on the Zoo Cloud, then Karamba3D needs to run from the same license account or team.
