I keep getting this error how do i fix it




The file was not found at the location the registry said it should be. The registry keys need to either be fixed or the game needs to be moved to the proper location.

You need to do this.

Since it's not clear what game you are playing, I will assume it's AOC. Please follow the steps mentioned here to perform a clean installation of the game:

For HD version, Please follow the steps mentioned here to perform a clean installation of the game:
http://support.voobly.com/display/vkb/KB1054+Clean+installation+of+Aoe2HD+with+compatibility+patch

If you are playing a different game, reinstalling the game to it's default location should fix the problem.
