How to install Windows Media Player 11 without Windows Authentication We receive a lot of emails about installing Windows Media Player version 11 on a computer that has not passed Windows authentication. The problem is that when you download Windows Media Player version 11 from a Microsoft server (wmp11-windowsxp-x86-enu.exe) so during installation your welcome to Windows authentication. The joke is that ... ... the authentication mechanism is only in the installation package (wmp11-windowsxp-x86-enu.exe), just rename this file to wmp11-windowsxp-x86-enu.cab and expand it using Total Commander, and then run wmp11.exe (Windows Media Player 11) and wmfdist11.exe (Windows Media Format 11 Runtime).
You can extract the files that are included in wmp11-windowsxp-x86-enu.exe by the following command line, without installing the Media Player:
wmp11-windowsxp-x86-enu.exe /T:c:\extract /C
l3codecp.acm is included in the extracted file wmp11.exe:
c:\extract\wmp11.exe /T:c:\extract\wmp11 /C
