I'm assuming you're on Windows.  If you're on Windows 10 you can use
creduce under WSL (Windows Subsystem for Linux) and have it call Windows
binaries.  You just need to make a change to make_tmpdir to use a temp
directory that Windows programs have access to.  I changed mine to:

sub make_tmpdir () {
    my $dir = File::Temp::tempdir("creduce-XXXXXX",
                                  $SAVE_TEMPS ? (CLEANUP => 0) : (CLEANUP
=> 1),
                                  #DIR => File::Spec->tmpdir);
                                  DIR => "/mnt/d/temp/");
    push @tmpdirs, $dir;
    return $dir;
}

Which points to D:\temp which I created for this purpose.  I know zero Perl
so I haven't made a proper patch to upstream, but hopefully this helps if
you ever need to reduce in the future.
