Anarchy Online is a very old game, and because of that issues of compatibility may sometimes occur with newer operating systems. If you’re experiencing issues running AO then please try these steps to see if compatibility issues are interfering. First, drag your entire AO installatino folder to your Documents folder and try running the game from there. If that helps resolve the issue then you may need to try reinstalling the game under the following conditions:
- Make sure you have User Account Control disabled
- Temporarily disable all antivirus/firewall software while installing
- Install the game to a custom location outside of the default file path
