Why can't I download Adobe Flash Player 11.1

I am useing Internet Explorer with  Windows 7 Professional and I have tried to access many sites which in turn informed me that I would need Flash Player 11.1 to allow me to continue. I have downloaded  Flash Player 11.1 at least twice and got the message that it was successfully downloaded  but it does not appear when I access "all Programs". I am useing a e-machines computer, Model ET 1810-03 which according to Belarc Advisor has  a 2.20 gigahertz Intel Pentium Dual-Core, 64 kilobyte primary memory cache, 1024 kilobytes secondary memory cache 64, bit ready,Multi -core(2 total), Not hyper-threaded. In my meanderings while trying to solve this problem I somehow remember seeing something somewhere that indicated that a processor faster than 2.20 was required to install Flash Player 11.1. I cannot find or remember where I saw the information about the processor. In any case, I would like to install Flashplayer 11.1. If my processor is inadequate I hope there is a work-around.
