error: Actionlist Not Found

Jeff, Thanks for contacting me. I've tried to download adobe flash player at least 20 times (seriously) from every sponser that you can imagine and after the initialization download I receive that messege, I've lived in the internet options area for 2 days and tried every prompt, security level, scripting attempt possible from the troubleshooting area of adobe. The computer I'm using was given to me while mine is being repaired by a friend of a friend who only knows that it was used by an elderly couple and I'm pretty sure it's windows xp or older. I've also tried to troubleshoot for internet explorer from the adobe site with no luck and one more thing, before I can reach the adobe site or any other site for that matter my browser turns light red and in forms me that there is a security certicate error and I have to click "go to site (not recomended) to go around it. I've tried my firewall settings etc. for that with no luck.
