Agent installation on Windows Server 2008 R2 ends prematurely because of an error

hashtag
Issue

Agent installation (or update) on Windows Server 2008 R2 failed with a "Xopero ONE Backup&Recovery Agent setup ended prematurely because of an error." message.

hashtag
Cause

Starting with version 1.9.6, Xopero ONE agent installation on Windows Server 2008 R2 requires the KB4457144 update. Without this update, the system lacks the necessary security components, causing the installation to fail.

hashtag
Resolution

  1. Visit the Microsoft Update Catalogarrow-up-right and download the version of KB4457144 that matches your processor architecture (x64 for most Windows Server 2008 R2 environments).

  2. Run the downloaded installer on the target machine.

  3. Restart the system (a restart is mandatory after installing this update to ensure all system components are correctly updated).

  4. After the system restarts, run the Xopero ONE agent installer again. The process should now complete successfully.

Windows Server 2008 R2 is a legacy operating system. Ensure that all other critical and security updates from Windows Update are also installed to maintain the highest possible level of security and compatibility for your backups.
