In the unlikely event that no useful accessors are defined in the LicenseInfo package, then you could directly access the properties like so by mapping the array into a hash or a hashref (chosen in this case to match the style of the licenseinfo)

foreach my $license (@licenseInfos) {
    my $licenseProperties = {map {$_->{name} => $_->{value}} @{$licens
+e->{properties}}};

    print $license->{customerName}, "\n";
    print $licenseProperties->{maxEngines}, "\n";

}
