Adobe Flash Player 10.3 update

I continue to get messages to load Flash Player update. I can load it easily from the official web site, and it works fine. As soon as I turn off my computer or reboot, I loose it and have to reload it again. If I go to the programs tab in control panel the icon for Flash Player is there, but windows won't recognize it. As soon as I reload it, it works fine. Why am I loosing the file every time I turn off the PC.?
