My window media player can’t play the DVD. Every time I insert DVD, there’s an error displayed; “%1 is not a VALID Win32 application.”
This thing never occurs before and it just about a week ago I GOT this error. Somehow the DVD can be opened in another music player.
I wonder what’s wrong with my window media player.
Can someone help me…

%1 refers to something stored in the computer


You could try to install the latest windows media player, hopefully that would helpthanks for the reply...but, I’ve updated my window media player earlier, seems that nothing’s change.
