Windows Media Center Mcupdate.exe Exception
» I just started having this error every time I try to run mcupdate.exe from within Windows media center or directly I get an unhandled exception (validOperationExecption.D0F96A43) occurred in mcupdate.exe 
validOperationException.D0F96A43 was unhandled.
EXE files allow users to launch programs without needing additional software on the user's computer special software. The exe file is one of the most useful types of files precisely because it runs programs; however, it can be used as a delivery system for viruses or other malicious programs. Viruses(TrojanDownloader:Win32/Beebone.GH) often reside to .exe files, which are then re-named to resemble common software packages.

a. Click the Start button, click Control Panel, click Programs, and then click Turn Windows features on or off.
b. From the list find "Media Features" and expand it. Turn off Windows Media Center by unchecking this option. Wait until the feature is disabled, click OK and restart the computer.
c. Once the computer is restarted, turn it on in the same way by checking the Windows Media Center back on. Check to see if the problem persists.

- CONSTANCE JACOBSON replied on January 23, 2013: » I believe the problem started maybe 4-7 days ago there have been no major installations on to the system or hardware changes. I have installed all the latest security patches from Microsoft in that time though.
I had actually done your method 2 right away to see if it was somehow corrupt but I wasn't able to find anything I removed the ‘Media Center' then added it in again and I'm still running in to the same unhandled exception.
When the file is open directly and I debug it I get this message repeated
First-chance exception at 0x000007fefd10aa7d in mcupdate.exe: 0xE0434F4D: 0xe0434f4d.

- CLIFFORD TOLOSA replied on January 26, 2013: » mcupdate.exe has never worked right on a new install of Windows 7 Ultimate. The only way I get guide updates in media center is to start an administrator command prompt, then execute MCUPDATE -u from \windows\ehome. It appears it won't run itself as an administrator and I can't figure out how to make it do it on its own. Every time I run mcupdate this way by hand it works, but it should run on its own.
