Can’t your emergency plan connect to the emergency engine? So you probably won’t find much help in my previous article on Crashplan, because backing up network sharing data or network storage devices with Crashplan is a whole other matter.

If you try to launch the Code42 application and the message “Code42 CrashPlan cannot connect to its background service” appears, this article can help you to troubleshoot. This error usually occurs because the Code42 service is not running.

Deleting previous files

If there are still previous installation files left, the error may be triggered. Therefore, in this step, we will delete the files previously installed. For that:

  1. Depending on the device, navigate to the following addresses.
  2. Windows Vista, 7, 8, and 10: C:\Users\<username>\AppData\<Local or Roaming>\CrashPlan
  3. Windows XP: C:\Documents and Settings\<username>\Application Data\CrashPlan
  4. Mac: /Users/<username>/Library/Application Support/CrashPlan
  5. Delete the”.ui_info” file in the folder and restart the Code 42 application.
  6. Check if the problem persists.
