Wibu cmu Tool
The Wibu cmu tool lets you read and configure information and settings of the locally installed CmRuntime.
The Wibu cmu tool (CodeMeter Command Line Utility) is an interface provided by Wibu-Systems to manage CodeMeter containers and licenses. License request files (*.WibuCmRaC) can be created and license update files (*.WibuCmRaU) can be installed. Diagnosis and maintenance work are also possible. The tool is primarily used to automate licensing tasks, especially in offline and scripted environments.
The cmu tool is included in the CodeMeter installation. The tool is available as a download from the official Homepage of Wibu-Systems.
On Windows, the cmu tool is located in the installation directory of CmRuntime (C:\Program Files\CodeMeter\Runtime\bin\).). To run the program, you need to use the terminal to navigate to this directory.
On Linux, the cmu tool is located in /usr/bin/ and therefore executable on most systems without having to navigate to the installation directory.
