Error code 193 is "bad exe format". Are your DLL and Racket both 32-bit or both 64-bit? (The text of the error message says "Unknown error" because the system-provided error text has a formatting command in it. I can make Racket show the error text with the formatting command, which will be ugly but more useful than showing only the error code.) ____________________ Racket Users list: http://lists.racket-lang.org/users
