Download links for the CLI can be found at the Release History.
After the file is downloaded, place the CLI in a folder that is included in your $PATH environment variable list of paths, typically /usr/local/bin. Open the Terminal application, navigate to the directory where the downloaded CLI file is located (usually your Downloads folder), and run the following command to copy the CLI file to the appropriate folder. If you do not have write access to your /usr/local/bin folder, then you may use sudo prior to the cp command. For example:
If you do not have sudo access on your system, contact your administrator for installation. Alternately, you may place the file in an alternate location and update your $PATH to include this location (see the documentation for your shell to determine how to update this environment variable).
You will also need to make the file executable so that the CLI can run:
You will likely want to place the CLI in a folder that is included in your $PATH environment variable list of paths. In Windows, you typically want to save your applications in the C:\Program Files folder. If you do not have write access to that folder, then open a CMD window in administrative mode (hold down the SHIFT key as you right-click on the CMD application and select "Run as administrator"). Type in the following commands (assuming you have saved ica.exe in your current directory):
Then you make sure that the C:\Program Files\Illumina directory is included in your %path% list of paths. Please do a web search for how to add a path to your %path% system environment variable for your particular version of Windows.
