This is an advantage over installing the whole of the DivX 3.11 pack because it installs its older video codecs which you do not need and it overwrites the registry and uninstall information which makes it impossible to uninstall DivX 3.11 Alpha and the other later DivX codec version you might have separately. So now you've got an unique DivX 3.11 Alpha repack that will install only the missing audio decompressor, will add an item in your audio compression manager (for win 9x - control panel / multimedia / devices / audio compression codecs) and also an option for uninstallation from control panel (add/remove programs).

The only available appropriate DivX audio codec comes with the DivX 3.11 alpha codec installation pack (other repacks also) - DivXa32.acm. In such cases your player starts searching the net for the appropriate codec and never finds it because there is no such available for download. Some movies are created with WMA sound format which is unrecognizable by the mp3 codecs of DivX versions higher than 3. If you are using a DivX codec 4, 5 or later for playing DivX 3 contents and you do not have the DivX 3.11 Alpha codec installed this is a tool that you might need.
