NS_E_WMPBR_BACKUPCANCEL
Diagnosing NS_E_WMPBR_BACKUPCANCEL during Windows Media rights backup or connectivity
NS_E_WMPBR_BACKUPCANCEL (0xC00D1131) is returned when a DRM license backup operation was canceled before it committed a complete backup set.
Preserve one asynchronous operation record containing the selected path, event listener, network resource and license-store status. In this case, the failure condition is a DRM license backup operation was canceled before it committed a complete backup set.
Safe controlled retry
- Freeze the current object state and collect cancel source, last WM_BACKUP_RESTORE_STATUS stage, destination path and files written before cancellation.
- Reproduce this result once without automatic retries or fallback applications.
- Change only one precondition: run a backup to a new empty directory and allow the completion callback to arrive before closing the Player.
- Compare the first nested status and next Player event with the failed run.
- After testing it, restore the original configuration if the change was diagnostic only.
Interpreting completion
| Retest outcome | Interpretation |
|---|---|
| A later HRESULT appears | The rejected condition — a DRM license backup operation was canceled before it committed a complete backup set — was cleared; diagnose the new code at its own layer. |
Actions that obscure the cause
- reusing a partial backup directory as if it were complete.
