Is the error coming from the game installer (AH2112.EXE), of from "aceshigh.exe"?
If it is from AH2112.EXE, then the download might have been corrupted. Can happen for a lot of reasons, the prominent one being an anti-virus program causing the corruption. If you are on AOL, you need to get some kind of download manager which will solve that problem.
If it is from the actual game itself, after it has been successfully installed, the I need to see the output from a DXDIAG. You can email that to me.
