Yesterday, I posted some information about a Group Policy setting that can prevent Windows Media Center from launching on a Windows Vista Home Premium or Ultimate system. Since then, I have heard from a couple of people who have been receiving the same error message but who did not have this Group Policy setting enabled on their systems. After some further investigation, I found another possible cause of this type of error that I wanted to describe here as well.
Description of the issue
To summarize some information from my previous post, it is possible that launching Windows Vista Media Center will fail and will instead display the following error message:
The dialog looks like this:
I looked at the startup code for Windows Media Center, and found that in addition to the Group Policy setting that I previously described, it is also possible for this error dialog to appear if Windows Media Center is marked as disabled in the Set Program Access and Computer Defaults control panel on Windows Vista.
How to work around the issue
You can use the following steps to enable Windows Media Center in the Set Program Access and Computer Defaults control panel if it is currently disabled:
Note - you do not have to select the radio button to the left of the Windows Media Center to make it the default media player if you don't want to, but the Enable check box must be checked or Windows Media Center will refuse to launch on your system.
What is happening behind the scenes
The Enable access to this program check box for the Windows Media Center Item in the Set Program Access and Computer Defaults control panel will result in the following value being changed in the registry on Windows Vista:
[HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Media\Windows Media Center\InstallInfo]IconsVisible
If the IconsVisible value is set to 0, then Windows Media Center will not run on a Windows Vista system.

In Windows 7 Pro. can you follow these same steps?
Hi Dutchman37 - Yes, it looks like the same steps apply equally to both Windows Vista and Windows 7.
apakah bisa langkah ini di gunakan di windows 8.1 pro?
Hi yuan - Yes, the information in this blog post should still apply to the version of Windows Media Center in Windows 8.1.
I've been trying this over and over again and I can't get it to work. There is one box that is greyed out.
Hi Braden - What version of Windows do you have on your PC, and what exact box is grayed out? Can you post a screenshot so I can try to take a closer look?
