C:\Program Files (x86)\MzScheme>MzScheme -m -f as.scm ffi-obj: couldn't get "setuid" from #f (The specified procedure could not be found.; errno=127)

=== context === C:\Program Files (x86)\MzScheme\collects\mzlib\ get-ffi-obj*

I get a prompt after it but not arc prompt i.e arc> . I tried keeping arc folder inside the MZScheme folder and also giving exact path to as.scm, but same result :(

It's completely normal that you're having issues. The official Arc documentation is...lacking.

The "latest" arc is Arc 3.1, but that came out in 2009. You can download it here:, and start it up with `racket -f as.scm`. (Note that you no longer need the specific version of MZScheme you used to; you can use racket.) No, this information has not been updated on the official Arc install page. Yes, this is frustrating.

Alternately, you have the option to use Anarki, the community-supported version. Documentation is here:
