NS_E_SETUP_IGNORABLE_FAILURE
Where the result originates
NS_E_SETUP_IGNORABLE_FAILURE means Windows Media setup completed its required core work but failed to install one or more optional skin or playlist components.
The result comes from the optional-content phase of the installer. A representative case is the Player binaries install successfully but an optional localized skin archive cannot be expanded.
Read the call sequence as a timeline. First, the application reaches the optional-content phase of the installer. Next, the component evaluates Windows Media setup completed its required core work but failed to install one or more optional skin or playlist components. A wrapper, user interface, or fallback path can report a less specific message afterward.
Evidence that survives retries
- Exact request: method name, all identifiers, units, flags, stream number, requested action, and this result.
- Object state: failed optional package, file path, signature, locale, disk or access result, core component versions, and setup log severity.
- Correlation: callback cookie, object instance, URL or file identity, device identity, and timestamps from the same attempt.
- Underlying cause: the first Win32, COM, network, driver, policy, or component error reported before
0xC00D2AFE.
A controlled verification sequence
Use one controlled experiment: start core playback and inspect the optional component list before deciding whether repair is necessary. A useful comparison for this result changes exactly that variable; changing content, account, proxy, device, components, and version together makes attribution impossible.
| Outcome | Interpretation |
|---|---|
| The same operation now succeeds | The changed precondition was relevant to the failure. |
| A more specific earlier HRESULT appears | Preserve it; this result was probably a wrapper or terminal state. |
| The operation advances and fails later | The condition is fixed even though the complete workflow still has another defect. |
| No behavior changes | Restore the original baseline and test another documented prerequisite instead of stacking workarounds. |
Nearby results that mean something else
| Related code | Why it is not interchangeable |
|---|---|
NS_E_SETUP_INCOMPLETE | Installation was not successful. |
NS_E_SETUP_BLOCKED | Installation is blocked because your computer does not meet one or more of the setup requirements. |
NS_E_REBOOT_REQUIRED | Installation was not successful; To continue, you must restart your computer. |
The important distinction is this: setup-incomplete indicates required components are missing and has a different operational impact. Use the symbolic constant and 0xC00D2AFE value to distinguish states that share a similar visible message.
Repair at the owning layer
Apply the narrow remedy: repair or omit the affected optional package; do not roll back a working core solely because an unused skin failed. Then discard stale media objects, pending callbacks, cached provider sessions, or installer state as appropriate and rerun the exact request that originally returned it.
