I've had the same problem with Media Center on my computer. After
uninstalling iTunes (I don't know if it's possible to keep iTunes or
not) I contacted microsoft and they gave me these
2 suggestions. They worked for me, hopefully they will for you too.
This issue can usually happen if there is any corrupted components of
Windows Media Center (MCE) or there is any third party software which is not
compatible with MCE. I suggest we use the following steps to check the
following related components.
Suggestion 1: Check the dependency services
======================
1. Click Start Pearl, type "services" (without quotation marks) in the
Search Bar and press Enter to start Services.
2. In the right pane, please check whether the following five services have
been started and the 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
If not, please double click the service. In the tab "General ", make sure
the "Startup Type" is "Automatic". Then please click the button "Start" under
"Service Status" to start this service.
Please have a check if the issue persists. If still the same error, let’s
try register the related dll files.
Suggestion 2: Register DLL files
==================
To resolve this issue, re-register jscript.dll, vbscript.dll and wmp.dll
using the following steps.
1. Close Windows Media Center and any other windows.
2. Click Start, All Programs, Accessories
3. Right click "Command Prompt" and choose "Run as administrator", accept
the UAC prompt.
4. Type the following commands and press Enter after each line.
regsvr32 jscript.dll
regsvr32 vbscript.dll
regsvr32 wmp.dll
exit
However, if the issue persists after we try the steps above, it can be a
complicated issue, the troubleshooting may be time-consuming.
