1Windows Media Center eHome LogoSolution to Media Center Library Error

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

1. Unin­stall oth­er apps which seem to inter­fere…

  • Zune
  • Nero
  • iTunes

2. Check that the appro­pri­ate ser­vices are run­ning and set to auto­mat­ic…

  • Click Start, type “services.msc” (without quo­ta­tion marks) and press enter
  • Check the fol­low­ing ser­vices are star­ted and that their star­tup type is Auto­mat­ic:
  • Cryp­to­graph­ic Ser­vices
  • Port­able Device Enu­mer­at­or Ser­vice
  • Win­dows Audio
  • Win­dows Driver Found­a­tion — User-mode Driver Frame­work
  • Win­dows Media Play­er Net­work Shar­ing Ser­vice
  • Win­dows Media Cen­ter Ser­vice Launch­er

3. Switch Media Play­er to the x64 ver­sion by default (64bit Win­dows only)

  • Click start, type “cmd”, right click on the search res­ult and select run as admin­is­trat­or
  • In the com­mand prompt type unregmp2.exe /SwapTo:64
  • Then type exit to quit the com­mand win­dow

4. Re-register 3 required dll’s

  • Click start, type “cmd”, right click on the search res­ult and select run as admin­is­trat­or
  • In the com­mand prompt type each of the fol­low­ing lines
  • regsvr32 jscript.dll
  • regsvr32 vbscript.dll
  • regsvr32 wmp.dll
  • Then type exit to quit the com­mand win­dow

5. Clear Media Cen­ter and Media Play­er Lib­rar­ies

  • Click on start type “%systemdrive%\ProgramData\Microsoft\eHome”
  • Delete mediacenterdatastore.db
  • Click on start, type “%LOCALAPPDATA%\Microsoft\Media Play­er”
  • Delete all files and folders

6. Repair Media Play­er

  • Click start, type “cmd”, right click on the search res­ult and select run as admin­is­trat­or

7. Repair sys­tem files

  • Click start, type “cmd”, right click on the search res­ult and select run as admin­is­trat­or

  • Turn win­dows fea­tures on or off
  • Untick Media Cen­ter and click ok
  • When unin­stall is done, retick media cen­ter and click ok to rein­stall

Hi
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!!
