NS_E_ASX_INVALIDVERSION
Understanding NS_E_ASX_INVALIDVERSION in a Windows Media playlist
NS_E_ASX_INVALIDVERSION (0xC00D106A) is returned when the ASX version declared by the document is newer or otherwise unsupported by the installed parser.
Distinguish in-memory Playlist state, WPL or ASX parsing, nested-list expansion, Media-object resolution and execution of referenced items. The relevant condition is the ASX version declared by the document is newer or otherwise unsupported by the installed parser.
Minimal playlist experiment
- Capture the resource identity and the VERSION attribute, Player version, compatibility mode and any vendor-specific elements.
- Verify that the caller uses the current Playlist, Media, Network, graph, device or DRM object instance.
- Run the narrow experiment: set the document to a version supported by the target Player and remove extensions while preserving one playable REF.
- Do not combine this focused test with a codec-pack change, Player reset, or broad registry cleanup.
- If the retest returns a different specific HRESULT, diagnose that new failure as the next stage.
What the result means
| Retest outcome | Interpretation |
|---|---|
| A later HRESULT appears | The rejected condition — the ASX version declared by the document is newer or otherwise unsupported by the installed parser — was cleared; diagnose the new code at its own layer. |
Actions that obscure the cause
- deleting the VERSION attribute without checking which elements require it.
