If I install Adobe Flash Player 10 will it change my pc settings or effect it in anyway.?

I wanted to watch a TV show that I missed, so I went into Fancast and it said that I would have to install Adobe Flash Player 10 to view it.If I install Adobe Flash Player 10 will it change my pc settings or effect it in anyway.?Other than add Flash Player to your browser as something the browser has access to, no. If you want there to be no sign on your computer that it's installed, you can't do that. If you're wondering if it will cause a problem, it won't. Millions of people have it installed, and have since it came out.
