I am trying to use DOSBox to run "The Best of Windows Games". I extracted all the files to the hard drive (files were on a compact disk that was made for this method in mind). I used the regular steps and everything seems fine except when I try to run any of the .exe files I get the message "This game requires Microsoft Windows". Well I'm using Windows 7 64-bit! (That's why I'm using DOSBox to begin with.)

All disk requirements are met. No corrupted files. Checked that files are NOT read-only. I'm running DOS on an administrator account. Usual game launch method being used from DOSBox Wiki from Hard Drive (Not root folder of C drive).
