The installer tries to check for the presence of Windows Media Player 9 by checking the DLL version of wmp9.dll. This doesn't seem to work, even after installing wmp9 from winetricks.
When the installer fails to detect Windows Media Player 9, it should display a request for the user to download the WMP9 redist, but instead the installer fails silently.
Hacking the installer by removing the launch condition check allows installation to proceed.
