Vista and 7 x64 Audio Codec Problem

Problem:
An important audio codec is missing from 64bit versions of Windows Vista and Windows 7. Some media files generate an error when using Windows Media Player. Third party media players seem to be affected as well, since some will play the video portion with no audio, and others won’t play the media file at all. This problem even occurs with media files downloaded from Microsoft. The Windows Media Player specific error is: “Windows Media Player cannot play, burn, rip, or sync the file because a required audio codec is not installed on your computer.”

Clicking on the “Web Help” leads you to the following page which isn’t much help: http://www.microsoft.com/windows/windowsmedia/player/webhelp/default.aspx?&mpver=12.0.7600.16385&id=C00D11C7&contextid=68&originalid=C00D0BC2 .

Solution:
Download the ACELP.net Codec by VoiceAge from http://www.acelp.net/acelp_eval.php and install it. The codec listed for Windows Vista x64 appears to work fine on Windows 7 x64.

    I’ve been searching everywhere on the internet to find this solution. This quick and simple fix has made my day. You’ve done what Microsoft couldn’t achieve… a way to make things work.

    At first I thought that dodgy looking self shot spelt a dodgy site but you’ve come through with the goods. You’re a legend Mike 🙂

    I had trouble with older .wmv files on Win7-64. Your suggestion solved the problem. You are “The Man!”

    Voice Age no longer offers the codec. Any idea where to find it from a safe and reliable codec site?
