Known Issues

Link issues with Internet Explorer

Note: If you install Internet Explorer 5 after you have installed the Player, you should run Windows Media Player Setup again. This will add the Windows Media plug-in to the browser so you can play Windows Media-based content that is embedded in Web pages.

Licensed files and Mac OS 8.1
Licensed files are digital media files that have been secured from random distribution by attaching a license that is required to play the file. Content providers, such as recording companies, can protect their files so they are less likely to be illegally copied and redistributed. Windows Media Player does not support playback of licensed files on computers running the Mac OS 8.1 operating system. To play licensed files, install Mac OS 8.6 or later.
