Something wrong with my Karamba3D in Rhino8 or Rhino7

Dear Everyone,

I have encounterd something serious problem with Karamba3D in the lasted versions of Rhino7 or Rhino8 in my PC.

  1. When I only install Karamba3D 3.1.50121.0 in Rhino7 or 8, and open GH the message will be :


    Later, when I drag out the License (karamba3D) componet, it will be:

    More, after I get the cloud license with “Karamba3DGetLicense”, the license is still “trial”.

  2. When I also installed Evolute Tools Pro, more serious problems come!


    I have renamed all the “libiomp5md.dll” as “libiomp5md.dll.backup” and installed “w_dpcpp_cpp_runtime_p_2025.0.0.1166.exe” and “w_ifort_runtime_p_2025.0.0.1166.exe” from the Intel Redistributable Libraries websited, just as “‘libiomp5md.dll' in EvoluteTools cause Rhino to crash - #2 by Kristjan_Nielsen” said, but nothing changed:(

Dear @edwardyanxin,
sorry for the inconvenience!

I believe there are three distinct issues to address:

  1. Speckle Export Message:
    This message appears because the latest version of Karamba3D includes an export feature for Speckle. The exporter is provided as a separate plug-in, which raises an exception if Speckle is not found on your system. However, this message is not critical and does not affect the functionality of Karamba3D.
  2. License Fetching Issue:
    The second message relates to difficulties in retrieving the license from the Zoo Cloud server. It’s possible that a firewall on your computer is blocking Rhino’s outgoing requests. Since Karamba3D only initiates the licensing process, which is ultimately managed by Rhino, I recommend searching for a solution to this issue on the McNeel Discourse forum.
  3. EvoluteTools Compatibility Problem:
    The known incompatibility between EvoluteTools and Karamba3D arises because EvoluteTools relies on an outdated version of libiomp5md.dll. To resolve this, locate the libiomp5md.dll file in your Karamba3D installation folder and replace it with the version that comes with EvoluteTools.

I hope this information helps!

Dear Clemens,

Thanks for your kind answer. I have replaced all the libiomp5md.dll files in Karamba3D with the one in Evolute Tools


And the previous third picture does not appear,BUT it seems that there are still some problems about the components?

Dear @edwardyanxin,
please replace the “libiomp5md.dll”-version in the evolute tools with that of Karamba3D. The latter one is more up-to-date and should be downwards compatible.
