I have recently installed Windows XP and also updated it to the latest windows update. But even after that WMP 11 wont install even when I try to download and install it from the microsoft site and instead I get an error message saying that "Unsupported Operating System" and "To install Windows Media Player 11, your computer must be running Windows XP Media Center Edition 2005 or later". Can anyone please help me out with this problem? Thanks
After some more try, I have now installed the Windows Media Player 10 version and whenever I go to install the WMP 11 version from the Windows Update then the installation will just fail and it will give me an error message: 0x80070643: Windows Media Player 11. Can anyone try to figure out what does this error means?
As per the question that you have raised it seems to me that you have used a Media Center operating system product key with a Windows XP installation CD and therefore your system might be terribly confused right now. Could you please tell me how did you get into that kind of problem?
I guess that you should run the "Update Rollup for Windows XP Media Center Edition" from here - http://support.microsoft.com/?kbid=925766 for the media center 2005 pc before installing the windows media player 11. To obtain the October 2006 Update Rollup for Windows XP Media Center Edition 2005, you can download it from the link that is given in this post.
The error code that you have listed may occur if the MSI software update registration has become corrupted, or if the .NET installation on the computer has become corrupted.
