NS_E_WMG_PREROLLLICENSEACQUISITIONNOTALLOWED: what the result means
NS_E_WMG_PREROLLLICENSEACQUISITIONNOTALLOWED (0xC00D104D) means a playlist preroll path attempted to acquire a content license at a stage where license acquisition is not allowed.
What to capture
Record which queued item first required a license, whether rights were already present before preroll, and the transition from playlist preparation into preroll.
Focused verification
Acquire or validate the required rights before entering preroll, then repeat the same queue operation. Do not treat a later license-server error as equivalent to this call-order restriction.
