Once you run the updater, you should be met with a GUI on Windows or a text-based menu on Linux. If you get an error that is not a recognized command, then you will need to either update your system environment Path variable or you can specify the full path to the java executable. When you’re finished downloading the file and launching an administrative command shell, run the below command. On Linux, use sudo to escalate your privileges. Next, you’ll want to launch the updater with administrative privileges. If you don’t have access to the ColdFusion admin, you can download the update manually from Adobe on the ColdFusion Updates page. Important: make note of where the file is downloaded to because you’ll need it later. This will automatically download the latest hotfix/update for your version of ColdFusion. The easiest way to accomplish this is within the ColdFusion admin by opening the Server Updates page and clicking Download next to an available update. The first step in manually updating ColdFusion is to get the updater jar file itself. The updater will also take its own backups and includes an uninstaller.jar file for rolling back updates, but we recommend taking another backup just in case something goes wrong with that process. This is usually as simple as copying the ColdFusion install directory to another location.

We strongly recommend that you backup your ColdFusion install just before installing the latest update.
