NS_E_WMP_UPGRADE_APPLICATION
Diagnosing NS_E_WMP_UPGRADE_APPLICATION in the Windows Media Player playback path
NS_E_WMP_UPGRADE_APPLICATION (0xC00D11CC) is returned when the installed Windows Media Player application or shared components are inconsistent and require repair or upgrade.
Diagnostic discriminator: Record Windows Media Player and shared-component versions and hashes before repair. If the same media succeeds after repairing or upgrading those components without codec changes, the inconsistent application installation—not the content format—was the relevant state.
Actions that obscure the cause
- installing third-party codecs as an application repair.
