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.
For NS_E_ASX_INVALIDVERSION, distinguish in-memory Playlist state, WPL or ASX parsing, nested-list expansion, Media-object resolution and execution of referenced items. For NS_E_ASX_INVALIDVERSION, the actionable checkpoint is the ASX version declared by the document is newer or otherwise unsupported by the installed parser. Although NS_E_ASX_INVALIDVERSION may appear as “cannot play” or “cannot save,” it belongs to a specific object state that should be diagnosed directly.
Playlist boundary
AllStat already supplies the standard user-facing description for NS_E_ASX_INVALIDVERSION; this custom block instead isolates the additional technical boundary. Earlier success in file lookup, network connection, parser creation or graph construction does not prove that the later NS_E_ASX_INVALIDVERSION operation is valid.
Case-specific checkpoint: the VERSION attribute, Player version, compatibility mode and any vendor-specific elements. The controlled comparison for NS_E_ASX_INVALIDVERSION is: set the document to a version supported by the target Player and remove extensions while preserving one playable REF.
Closest distinction: NS_E_ASX_INVALIDFORMAT means the structure is malformed even before version-specific behavior is considered.
Evidence from the list model
| Capture | Why it matters for NS_E_ASX_INVALIDVERSION |
|---|---|
| Object or resource | the VERSION attribute, Player version, compatibility mode and any vendor-specific elements |
| State snapshot | Record the Player openState/playState or operation phase, object identity and exact timestamp when NS_E_ASX_INVALIDVERSION was returned. |
| First lower result | Keep the earliest Win32, Winsock, COM, parser, codec, DRM or device result that appears before NS_E_ASX_INVALIDVERSION. |
| Comparison record | For NS_E_ASX_INVALIDVERSION, use one known-good case that follows the same API, protocol and component path while changing only the rejected precondition. |
Minimal playlist experiment
- Capture the resource identity and the VERSION attribute, Player version, compatibility mode and any vendor-specific elements.
- For
NS_E_ASX_INVALIDVERSION, verify that the caller uses the current Playlist, Media, Network, graph, device or DRM object generation. - 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 mix the
NS_E_ASX_INVALIDVERSIONexperiment with a codec pack, Player reset or broad registry cleanup. - After
NS_E_ASX_INVALIDVERSION, treat a new specific HRESULT as evidence that this boundary was cleared.
What the result means
| Retest outcome | Interpretation |
|---|---|
| Same NS_E_ASX_INVALIDVERSION on the same object | For NS_E_ASX_INVALIDVERSION, the governing state or value is unchanged, or the caller is reusing an object created before the relevant change. |
| Fresh object succeeds | Lifetime, cached configuration or stale playlist/graph state contributed to NS_E_ASX_INVALIDVERSION. |
| 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 for NS_E_ASX_INVALIDVERSION; diagnose the new code at its own layer. |
| Only one item or endpoint fails for NS_E_ASX_INVALIDVERSION | For NS_E_ASX_INVALIDVERSION, the evidence favors resource-specific data, rights, routing or device state rather than a global Player failure. |
Actions that obscure the cause
- deleting the VERSION attribute without checking which elements require it.
- Do not discard the first
NS_E_ASX_INVALIDVERSIONoccurrence by repeatedly invoking Play, open, save or retry; later events can replace its original state. - For
NS_E_ASX_INVALIDVERSION, do not publish credentials, private URLs, license material or complete protected-content headers; retain only redacted identifiers, lengths, hashes and protocol fields.

The NS_E_ASX_INVALIDVERSION fix is demonstrated by the same Player path succeeding with the same resource, not by another application opening it.
