If those files are missing, download the official Miles Sound System SDK from RAD Game Tools (now part of Epic Games) – not from a “CoD2 error fix” site.
The persistence of this error highlights a significant issue in the gaming industry: the abandonment of legacy software. Call of Duty 2 is not freeware; it is a paid product owned by a massive corporation (Activision). However, the official support infrastructure for the game has largely evaporated. The official dedicated server browsers have shifted or shut down, and the original disc versions struggle to function on modern PCs without community patches.
This vacuum forces preservation into the hands of the community. Sites like ModDB or specialized forums often host the true fixes—patch 1.3, nocd cracks that are actually compatible with modern systems, or tweaks to compatibility settings. The "exeerrmssinitfailedmp" error is essentially a symptom of a broken supply chain. The publisher no longer sells the game in a format that works natively on modern systems, forcing users to pirate it, where they encounter errors that drive them to search for risky "fix" links.

Some sites claim CoD2 is abandonware, but Activision still sells it. Downloading from these sites carries the same risks as described above.
