QuickTime Alternative is a codec package for Microsoft Windows for playing QuickTime media, normally only playable by the official QuickTime software distribution from Apple Inc. [1] Development has now ceased and the version of the QuickTime codec now lags behind that released by Apple.
The last version that is compatible with Windows 2000 is version 7.10. The last version that is compatible with Windows 9x is version 3.45.
