Okay assuming you are using winVista/7 etc. Go to the folder you have hack-ace in, don't open it, right click on it and select "Copy Path" now go to Start>Type Cmd>Right click>Run as Admin, then when the terminal opens type CD and then paste the path you copied by right clicking and selecting paste after that press enter, now just drag the hack-ace file into the terminal. Hope this helps.
