I understand I am not alone in finding that WMP 12 persistently refuses to open (instantaneous error message is 'server execution failed'). I believe that I have covered all the recommended 'solutions' and none of them work. Attempts to reinstall WMP appear nugatory as the standard procedure simply disables the program and then reopens it. I have installed VLC Media Player and that works just fine as a substitute, but this seems a poor outcome for one of the flagship facilities on Windows 7. WMP 11 apparently suffered none of these problems. Any comments please?
