ERROR_SXS_PROCESS_TERMINATION_REQUESTED

ERROR_SXS_PROCESS_TERMINATION_REQUESTED — A component participating in Side-by-Side activation requested that the process be terminated.

This status signals a fatal failure in an isolation component. The code usually follows a more specific SideBySide, manifest, or component-store error that explains why continuing would be unsafe.

Look for the first related error and preserve the trace before retrying. Simply restarting the process may reproduce the same activation failure.

What to check

  • Collect the SideBySide event log and an sxstrace capture for the failing application.
  • If the issue is limited to one application, repair or reinstall its complete package.
  • If Windows components are involved, check component-store health before applying servicing repairs.
