A couple of days ago I started getting an error on my HTPC when I tried to change library locations — either adding or removing. Media Center shows the error which says “A necessary component of windows media center did not start properly. Restart windows media center”. I understand this error can also affect Media Center Extenders
Some googling resulted in about 30 links. It seems this error can be caused by a variety of problems which I will attempt to list below in case the solution that worked for me doesn’t work for you. Eventually, thanks to an anonymous poster on windows experts, I solved my problem by running Windows Media Center as administrator, going into the edit library settings, quitting back out and rerunning as normal.
If for some reason this doesn’t work for you, here are a list of other options that other people have found helpful

I had the same issue with my WMC. Also acessing WMC picture and video libraries closed WMC. I also noticed IE was closing immediately on launch.
i tried running WMC as Administrator and this worked, however did not resolve when i ran as a normal user — albeit that user was an admin user. I then tried Windows repair at major geeks and this did resolve all!!
