'Service Registration Failed' Error During Installation

This Article Applies to:

  • Avast Business CloudCare


In the event you or a customer receives an "Service registration failed" error message during Business Agent installation on a device, this could be due to software restriction policies that have been placed on the device, usually by some malicious or unwanted software.

Resolving this issue

Take care when editing the registry, as an incorrect change can lead to serious problems. Export any keys you plan to make changes to in case you need to restore them.

  1. Check the following registry key on the device: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\safer\codeidentifiers\0\paths
  2. You should find a sub-key that contains ItemData of C:\Program Files\Avast Software, which prevents Avast from installing
    • The sub-key will be an ID within {*}, e.g. {e37cdf1c-d301-4aa5-b828-1fc92be6db7f}
  3. Delete the key (there may be multiple registry keys containing other restrictions to block AV software)
  4. Once removed, rerun the installation package and CloudCare Antivirus will proceed to install correctly

If there are some legitimate restrictions in place, please contact your system administrator.
