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.
