This article is intended for CrashPlan for Home users. For Code42 CrashPlan and CrashPlan for Small Business documentation, read this page on our enterprise support site.


This article explains how to uninstall the CrashPlan app from your computer.

Uninstalling the CrashPlan app 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 Customer Champions before uninstalling.

Standard uninstall

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


  1. Open the Control Panel, and select Uninstall a Program.
  2. Select CrashPlan for Home 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 CrashPlan app from uninstalling completely. Code42 recommends coordinating with other users to ensure all users are signed out of the account before continuing.
