Guest JMVL Posted July 26, 2007 Posted July 26, 2007 Current system: Windows Vista Ultimate RETAIL installed onto clean system. UAC disabled Using full administrator account w/ no restrictions Problem: Anytime I attempt to launch Windows Media Center or Media Center Extender I receive the following popup error and the program does not attempt to to even start: Error: [Windows Media Center] "Windows cannot open this program because it has been prevented by a software restriction policy. For more information contact your system administrator." Summary: When I initialy installed the OS, this problem did not exist. I was able to launch WMC just fine. Only after a couple month of reinstalling necessary base applications do I now get this error. My family cannot even use it as an extender for the XBOX360 anymore. From what i can tell there are a lot of people with this issue and <u>NO SOLUTION from MS as yet</u>. I did see in one post that someone else had this error and was able to correct it by setting WMC as the default application in "Default Programs --> Set Program Access and Computer Defaults" This did not work for me at all. At this point I am at a complete loss. Any insight would be appreciated. -JML Quote
Guest P. Di Stolfo Posted July 27, 2007 Posted July 27, 2007 Hello, here's something you could try: Press Windows-key + R (so you have the Run... window) -> type gpedit.msc -> Enter. In the Group Policy Object Editor now, click Computer Configuration -> Administrative Templates -> Windows Components -> Windows Media Center -> "Do not allow Windows Media Center to run" -> Disabled . Please report if this worked for you. Greetings, P.

Guest JMVL Posted July 28, 2007 Posted July 28, 2007 Re: Windows Media Center -wont launch..due to software restriction P, That was one of the first things that I tried as well however it did not work. Also, I have no local secpol restrictions setup either. I temporary enabled the local policy and granted unlimited access to the \ehome and windws start menu folders as I saw on another thread that launching programs from the start menu may be disabled by default. Still no good. The main response that I keep seeing about this issue comes back to the default progams settings (which others claim sometimes worked) For me, no matter what I change these settings to beit "Microsoft, Non-Microsoft or Custom", still the same issue. I have tried disabling all of the non-MS and setting the defaults on WMC and making it the default app again in every combination etc.. The only other thing I can think of is other media players installed on this system may be conflicting. Currently iTunes, Winamp and Realplayer (as well as the default Media Center and Media Player) are installed. However uninstalling or disabling any of these access in default programs did not work. -J "P.

Guest mawilliams47 Posted December 19, 2007 Posted December 19, 2007 After much searching on the the net i found this solution... control panel > default program > set access and computer defaults > custom > choose a default media player. For me it displayed; Quicktime windows media center windows media player unchecked everything, applied thoses changes. the rechecked them, applied those changes. media center icon now appears in the START list, and now loads up.... I hope it works for you style_emoticons/ -- mawilliams47 Quote
