When you install a third-party product that registers its own version of the Wmp.dll file on a Windows Vista-based computer, Windows Media Player stops responding.

CAUSE

This problem occurs because the third-party product uses its own installation directory to install the Wmp.dll file on the Windows Vista-based computer. When this occurs, the InstalledVersions corruption check that Windows Media Player performs is bypassed and Windows Media Player is blocked or stops responding.
