Unable to download an appropriate decompressor. (Error=80040200)


CAUSE

This error message can occur for any of the following reasons:

  • Microsoft Internet Explorer version 3.02 or later is not installed on your computer. Internet Explorer is required to install decompressors, which are files that enable you to play multimedia content. Although Internet Explorer is required to download decompressors, it does not have to be set up as the default browser.


  • Your Internet security options are set too high to allow decompressors to be downloaded.


  • Installation of the decompressor requires a restart of your computer but no restart occurred.


  • The codec required to play the file is missing or damaged.


  • You may be playing a file format that is not supported by Windows Media Player.



RESOLUTION

  • To install the latest version of Internet Explorer on your computer, see the following Microsoft Web site:


  • http://www.microsoft.com/ie/download
    Note that Internet Explorer 5 is included with Windows 98 Second Edition. Do not attempt to reinstall Internet Explorer 5 in Windows 98 Second Edition.

  • To lower the Internet security level to medium, follow these steps:

    1. Click Start, point to Settings, and then click Control Panel.


    2. Double-click Internet.


    3. On the Security tab, click Internet.


    4. Under Security Level For This Zone, move the slider to Medium or lower.


    5. Click OK.




  • Restart your computer and try to play the file again.
