4.1.1: Installation Issues

Rhino Developer error message

After installing Karamba3D and on Rhino startup, a pop up showing an error of the Karamba3DLicense appears: "CRhinoLicenseValidator object registration error. A Plug-in can only have one CRhinoLicenseValidator-derived object."

This error occurs when you have installed Karamba3D using both the program installer as well as using the YAK Package Manager.

To resolve this issue, either remove Karamba3D from the Package Manager or uninstall Karamba3D in your Windows Program List.

Karamba3D Component Library was build against a newer minor version of the Grasshopper SDK

After installing Karamba3D, and loading Grasshopper, if this pop up appears in your Rhino window, this means your Rhino Version is currently not up to date.

Simply go to the Help menu in Rhino and click on Check for Updates...

Karamba3D for Rhino8 Mac does not seem to show up

Karamba3D needs to run with Rosetta (Intel) in order for it to work on Rhino8.

Select the app's icon in the Finder.
From the File menu in the Finder menu bar, choose Get Info.
In the Info window that opens, look for the information labeled Kind. If the kind is Application (Intel), the app needs Rosetta to work on a Mac with Apple silicon. If the kind is Application (Universal), the app doesn't need Rosetta, because it supports both Apple silicon and Intel processors.

Does not appear nor any of its components seem to be installed

Make sure to unblock the Karamba3D installation (*.msi) file before running the installation. To do this, right click on the file in Explorer and go to "Properties". If the file is blocked, there will be an option to "Unblock" the file at the bottom of the Properties Window.

Ensure that you install Karamba3D as an administrator.
Check the directory where Karamba3D is installed. It should be located in the Plugins folder of the Rhino installation. This is often C:\Program Files\Rhino 6\Plug-ins or C:\Program Files\Rhinoceros 5.0 (64-bit)\Plug-ins, however it can also be C:Program Files\Rhinoceros 5 (64-bit)\Plug-ins. Make sure the folders correlate otherwise Karamba3D will not appear in Grasshopper.
In case of multiple versions of Rhino on your machine make sure that you installed Karamba3D to that right version. Karamba3D can be installed for “Rhinoceros 5 (64-bit)”, “Rhino 6” and “Rhino 7” in parallel. In that case there will be three “Karamba3D” entries in the list of installed applications.
You can also navigate to the Plugins folder of your Rhino installation (C:\Program Files\Rhino 6\Plug-ins for example) and drag and drop the Karamba.gha file into your Grasshopper canvas.

Does not work after reinstalling Grasshopper

Upon installing Grasshopper some files of the Karamba3D package may have been erased. Try to reinstall Karamba3D.

Grasshopper Loading Errors in connection with Karamba3D plug-in

This error indicates, that the C++ library of Karamba3D is not loading correctly. This may have several reasons. Try the following:

The C++ library depends on 'libiomp5md.dll' which is the Intel openMP runtime-library used for parallelization. There are several applications (e.g. Evolute Tools) which use the same dll and usually come with their own - sometimes outdated - version of it. 'libiomp5md.dll' should be backwards compatible. Try to replace all copies of 'libiomp5md.dll' that you find on your hard disk with the latest version - for example the one which comes in the installation folder of Karamba3D.
If you get the above error message only when opening Rhino via double-clicking on a 3dm-file, then check whether you have a Rhino-Sofistik plug-in installed. Uninstall it and test whether the Karamba3D loading problem still persists.

DLL requirement on Windows 8

When installing Karamba3D on Windows 8, and an error message pops up stating ‘There is a problem with this Windows Installer Package. A DLL required for this install to complete could not run. Contact your support personnel or package vendor.’ do the following:

Make sure that you installed a Karamba3D version with the correct bitness: Karamba3D (64bit) can be used together with Rhinoceros 5 (64bit); Karamba3D (32bit) with Rhinoceros 5. Be aware of the fact that both versions of Rhino get installed.
Check to see if the installation file downloaded contains the *.msi extension. Sometimes Windows automatically adds an *.exe extensions to *.msi files.
Make sure that Windows is up to date.
Change the permissions to full access to ‘C:\Users\<username>\AppData\Local\Microsoft\Windows or C:\Users\<username>\AppData\Local\Temp’. Make sure that the hidden files and folders are shown in Windows. Open Windows Explorer and folder ‘C:\Users\<username>\AppData\Local\Microsoft\Windows or C:\Users\<username>\AppData\Local\Temp’. Right click on the folder, the Local Properties pop up window will appear. Select the tab Security. Click Edit, the Permissions for Local pop up window will open. On Group or \user names, select the desired user. Ensure that the Allow _check box for Full control is activated, else activate it. On the Permissions _for Local pop up window, click OK (if no changes were made) or Apply (if changes were made). On the Local Properties pop up window, click OK (if no changes were made) or Apply (if changes were made).
