Windows 2000 is not supported, officially reaching the end of it's life in June 2010.
We would recommend that you upgrade to an actively supported version of the Windows operating system.
The minimum system requirements for Flash Player can be found here: http://www.adobe.com/in/products/flashplayer/tech-specs.html
As a short-term fix, you may be able to run a version of Flash Player 10.3 from the Archives page, which is currently supported with security updates; however, your operating system remains vulnerable as it is no longer maintained from a security perspective.

You will need a hex editor and modify the installer.
Thank you Pat Willener, the aritcle was actually really helpful. But when I tried to install Flash Player a new message appear, "The exception unknown software exception(0xc0000417) occured in the applicatin at location 0x00412c90." Apparently Firefox has Real Player installed but I already uninstalled it and took the plugs in or add ons off. Still message appears. I give it up. I'm taking my computer to a tech.
