ActiveState perl512.dll error

[Generoso]

Dear monks I am trying to run an example on SimpleXLSX with ActiveState perl 5.0.16 and I get an error message that it can not fin perl512.dll.

My guess is that it sholud be using perl516.dll, why am I getting this error?

#!/usr/bin/perl -w

use strict;
use SimpleXLSX;

my $parser   = SimpleXLSX->new();
my $workbook = $parser->parse('Book1.xls');
if ( !defined $workbook ) {
    die $parser->error(), ".\n";
}
for my $worksheet ( $workbook->worksheets() ) {
    my ( $row_min, $row_max ) = $worksheet->row_range();
    my ( $col_min, $col_max ) = $worksheet->col_range();
    for my $row ( $row_min .. $row_max ) {
        for my $col ( $col_min .. $col_max ) {
            my $cell = $worksheet->get_cell( $row, $col );
            next unless $cell;
            print "Row, Col    = ($row, $col)\n";
            print "Value       = ", $cell->value(),       "\n";
            print "Unformatted = ", $cell->unformatted(), "\n";
            print "\n";
        }
    }
}

Result:
