how to find and activate my adobe flash player already installed by microsoft windows 10 OS

how do I find  Adobe flash player on my windows 10 operating system? When I tried to download Adobe player a message told me that I do have Adobe player with my windows 10 already on my computer, I just need to adjust it to permit or activate it, but cannot find the adobe player anywhere on my computer to activate it or make it to allow. So can you please help me find the adobe flash player download on my computer so I can activate it to allow any of my videos etc.

Thank you
