Uninstall the backup and legacy agent

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.

Legacy agent end-of-life
On April 10, 2024, the Code42 legacy agent reached end-of-life. Devices with the legacy agent are no longer backing up, and Incydr monitoring has stopped. Follow the steps in this article to uninstall the legacy agent from any devices that have not upgraded yet, then follow these steps to deploy both the insider risk and backup agents.

Standard uninstall

A standard uninstall removes the Code42 agent from your computer. An identity file is left on your computer in case you reinstall in the future.

Windows

  1. Open the Control Panel and select Uninstall a Program.
  2. Select Code42 and choose Uninstall.

You may be prompted that another user on the device is signed in. If another user is signed in, it may prevent the Code42 agent from uninstalling completely. Coordinate with other users to ensure all users are signed out of their accounts before continuing. 

Uninstall fails
If the uninstallation fails, follow Microsoft's instructions to fix problems that block programs from being installed or removed.

Mac

Code42 agent version 11.0 and later, and all versions running on macOS Ventura and later
  1. Go to Applications > Utilities.
  2. Open Terminal.app.
    The Terminal window opens.
  3. Enter the command corresponding to your installation type. If you plan to reinstall the Code42 agent, append --preserve-data-upgrade to the end of the command to prevent the agent from resending files that are already backed up:
    • Version 12.2 and later:
      • Installed for everyone (default):
        sudo "/Library/Application Support/CrashPlan/uninstall.sh"
      • Installed per user:
        sudo "~/Library/Application Support/CrashPlan/uninstall.sh"
    • Version 12.1 and earlier:
      • Installed for everyone (default):
        sudo /Applications/Code42.app/Contents/Helpers/Uninstall.app/Contents/Resources/uninstall.sh
      • Installed per user:
        sudo ~/Applications/Code42.app/Contents/Helpers/Uninstall.app/Contents/Resources/uninstall.sh
  4. Enter your password if prompted.
    The password doesn't display as you enter it.

The Terminal uninstalls the Code42 agent.

Code42 agent version 10.3.1 and earlier
  1. Open the Finder.
  2. Press Command+Shift+G.
    A dialog box appears: Go to the folder.
  3. Paste this text into the dialog box:
    • Installed for everyone: /Library/Application Support/CrashPlan/Uninstall.app
    • Installed per user: ~/Library/Application Support/CrashPlan/Uninstall.app
  4. Click Go.
    If you see the error "The folder can't be found", download the Mac installer and double-click the .dmg file to mount it before continuing to the next step. 
  5. Double-click Uninstall.
  6. Follow the prompts to complete the uninstall process.

Linux

  1. Download the Code42 agent.
  2. Uncompress the TGZ file in Downloads.
  3. Open Terminal and enter: cd ~/Downloads/code42-install
  4. Press Enter.
  5. Then enter: sudo ./uninstall.sh -i /usr/local/crashplan
    If you plan to reinstall the Code42 agent, append -x to the end of the command to prevent the agent from resending files that are already backed up.
  6. Press Enter.
  7. At the prompt, type YES to uninstall and press Enter.

Complete uninstall

A complete uninstall removes the Code42 agent, your computer's identity file, and any backups on your computer. Only perform a complete uninstall if:

To completely uninstall the Code42 agent:

  1. Follow the instructions above for a standard uninstall.
  2. Delete the following folder from your computer:
  • Windows:
    • If installed for everyone: C:\ProgramData\CrashPlan
    • If installed per user: C:\Users\<username>\AppData\<Local or Roaming>\CrashPlan
  • Mac:
    • If installed for everyone: /Library/Application Support/CrashPlan
    • If installed per user: ~/Library/Application Support/CrashPlan
  • Linux: /var/lib/crashplan

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. 
App Management permissions
Some versions of macOS Ventura may require you to grant additional permissions to the application you use to uninstall the agent (for example, Terminal). To add permissions:
  1. Go to System Settings > Privacy & Security > App Management.
  2. Click the plus + icon.
  3. Select the application you're using to perform the uninstall (for example, Terminal).
  4. After completing the uninstall steps below, you can remove this permission.

  2. Enter the administrator password for the computer and press Return. 
  3. Copy and paste the following commands.
    sudo launchctl unload /Library/LaunchDaemons/com.code42.service.plist
    sudo chflags noschg /Applications/Code42.app
    sudo chmod -R 755 "/Library/Application Support/CrashPlan/" 
  4. Open a Finder window and delete the following folders:

/Library/LaunchDaemons/com.code42.service.plist
/Applications/Code42/
/Library/Caches/CrashPlan/
/Library/Application Support/CrashPlan/
