What does HRESULT 0xC00D1262 (NS_E_BKGDOWNLOAD_FAILED_TO_CREATE_TEMPFILE) mean?

NS_E_BKGDOWNLOAD_FAILED_TO_CREATE_TEMPFILE

The failing boundary

NS_E_BKGDOWNLOAD_FAILED_TO_CREATE_TEMPFILE (0xC00D1262) is specific to allocating the local temporary file used by the Windows Media Player download manager. The transfer has not reached the final move or package-unpack stage.

What to capture

Preserve the resolved temporary directory, generated file name, volume free space, account used by the Player process, directory ACLs, and the first file-creation error. Also note whether the path exists and whether it resolves to the expected local volume rather than a disconnected or redirected location.

Useful controlled comparison

Create a small ordinary file in the same directory under the same security context. If that fails, fix the path, permissions, quota, or storage condition before retrying the media download. If manual creation succeeds, keep the path unchanged and inspect the name generated by the download manager and any security software that intercepts file creation.

Do not treat a successful network transfer as proof that this stage is healthy: this HRESULT is about local temporary-file creation.
