Do I need to install a C compiler maybe? This message comes from Windows. For some reason you are being prevented from running the DOS executable. I know you can get this message if your default directory is too long, or if you environment is too full. It may happen also if someone has set a policy against you running DOS images. 1) Make sure you have a short current directory, like c:\djgpp\bin 2) Run from a command line 3) Make sure your path is reasonably short, i.e set path=c:\windows\system32;c:\windows;c:\djgpp\bin 4) Remove unneeded environment variables: SET PROCESSOR_IDENTIFIER= 5) Try running as an administrator; check policy on running dos images
