KB886903 on Windows XP Media Center Edition 2005

I have been trying to install this update for quite some time, but it doesent
seem to work! The result is Error Code: 0x643 Try to install the update
again, or request help from one of the following resources.

My computer is extremely new and runs Windows XP Media Center Edition 2005.
Are their any known issues with this update on this edition of Windows XP.

Since this update was related to .NET Framework, I tried to uninstall it but
it does not allow me to - it throws another error.

Any help will be very useful. Thanks!

I had the same issue. There is another post on this site that helped me, Re:
problem with install of KB886903 -it has a date of 2/15/05. I wound up
getting back to net framework 1.0, updating to 1.1, but not the update;
installed the rollup 2 for MCE and the update to rollup 2; then installed the
KB886903 (knock on wood, it is working).
