From Free to Full Version, silent


Is there a way to change a free version in a full version silently?

We accidently rolled out the free installation on a huge amount of machines and a silent uninstall won’t work.


I have now managed to run the uninstall silent via the MSI code.

But a simpler way would be nice.

Hi, at the moment this is only method, but we will take this into consideration.

I just installed it via a batch file

start /wait “Install Karamba3D_2_2_0_17_RH7” msiexec.exe /i “%cd%\Karamba3D_2_2_0_17_RH7_221006.msi” /QN
echo f | Xcopy “%cd%\Karamba3D_License_2023_08.lic” “C:\Program Files\Rhino 7\Plug-ins\Karamba\License\licensePRO.lic” /Y

ran powershell to get msi string

Get-ChildItem -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall, HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall | Get-ItemProperty | Where-Object {$_.DisplayName -like “kara” }

then got the msi string and uninstalled it

start /wait “UnInstall Karamba” msiexec.exe /X {D882C96A-71A2-4351-951B-C22FBB66B018} /QN

REM Delete Folder
RD /S /Q “C:\Program Files\Rhino 7\Plug-ins\Karamba”


What switch did you use to get the TRIAL version to install ?

Hi, you can see it here: 1.1 Installation - Karamba3D 2.2.0
