With ` ` I do not have any failures in log.
I run: 
my @arr = `perl -w $solver_file "$inp_file" "$outfile"`;

[download]
$outfile is just an indication to print to STDOUT
I have Cygwin and ActivePerl on my machine which starts all pathes with /cygdrive/c/.
when I type "which perl" in DOS cmd I get
/cygdrive/c/ActivePerl/bin/perl
So I tried 
my @arr = `/cygdrive/c/ActivePerl/bin/perl -w $solver_file "$inp_file"
+ "$outfile"`;

[download]
instead but same result, @arr is empty.
