how to install flash player

OK, I have windows vista home premium 32 bit OS with Firefox 47 x86 as my default browser, and IE9. there is no version of flash player on my laptop. I can't play my Facebook games or even view a lot of web sites without being told I need the latest player, but when i try to install it the download pops up, it says it's installed, asks me if i want auto updates, then nothing happens.  I can see it in my programs but it has no numbers for the size. I've read threads from 2009 til the present with no help. can anyone solve this issue for me, please.
