Please note that NMIS must be installed on the your machine before opCharts or most other Opmantek Modules. Please ensure you have installed NMIS before installing opCharts. NMIS is the underlying software required to run any of Opmantek’s individual modules, and can be installed on Linux. If you do not have a machine currently running Linux, you can download and install the Opmantek Virtual Machine, which includes NMIS and all Opmantek software modules. The following installation guide should be sufficient for most users’ needs. Advanced instructions and troubleshooting are available on the opCharts Wiki.

Download the opCharts installer

If you haven’t already, hit the download button above and download the opCharts Installer. The Installer comes as a .run file.

Run the Installer in Linux Terminal

Open the Linux Terminal. Start a Terminal instance as the root user through the following command, entering your password when prompted: sudo -i If you have not been granted access to the root user, contact your system administrator. Once your terminal session is run by the root user, run the shell command to begin the installation process

 sh /…/opCharts-<version number>.run 

Press Y or Return/Enter when the installer prompts you.
