Done it and wmp does not install



Hello MRZAG
There is no way no reinstall WMP12 as its shipped as part of windows7. The nearest you can get is to turn it off/on in programs and features - http://www.sevenforums.com/tutorials/5023-windows-features-turn-off.html
Try running a system file check see if that finds anything - http://www.sevenforums.com/tutorials/1538-sfc-scannow-command-system-file-checker.html then turn it off reboot and turn on again. Its a bit hit and miss but may work.

GREAT RESPONSE!!!
I'm surprised that after 2 years, you havent just did a clean install of Ultimate.
Several guides exist to teach you how to use an upgrade dvd for a clean install.
