Windows Media Player 12 doesn't open up

I am using Microsoft Windows 7 Professional 64 bit.
Recently i have started facing this problem, whenever i click on Windows media player it will not open up or it will flash for a sec and close down.
I have tried uninstall and reinstall but it didn't help.

If i right click and run as administrator then it works, Other wise normal click it doesn't open up.

It doesn't not allow me to install the file.
