Overview
This article explains how to uninstall the Code42 agent from your computer. This article applies to the backup agent and legacy agent only. For the insider risk agent, see Uninstall the insider risk agent from user devices.
Uninstalling the Code42 agent removes the log files associated with your backups on this computer. If you're uninstalling as part of a troubleshooting process, send your log files to our Technical Support Engineers before uninstalling.

A complete uninstall removes the Code42 agent, your computer's identity file, and any backups on your computer. Only perform a complete uninstall if:
- You want to permanently end all Code42 agent backups for this computer.
- A Technical Support Engineer instructs you to do so.
To completely uninstall the Code42 agent:
- Follow the instructions above for a standard uninstall.
- Delete the following folder from your computer:
Manual uninstall for Mac
Perform the following steps if you were unable to uninstall the Code42 agent on a Mac using the directions provided above.
A manual uninstall is typically not needed on Windows or Linux. However, if you already tried to remove the Code42 agent on a Mac by a non-standard method, the normal uninstall process will error out if subsequently run. This is because the installation file is locked on a Mac and it must be unlocked (with a chflags noschg command) before it can be uninstalled.
Perform manual uninstall under Technical Support Engineer supervision
You should only perform these manual uninstall steps under the supervision of a Technical Support Engineer. If run improperly, the commands have the potential to cause harm to your system.
