In the VB code you pass two parameters to the RLVersion(), you should do the same in Perl. You just need to tell Win32::OLE that you want that parameter passed by reference. Something like this might help: 

use Win32::OLE::Variant;
my $y = Variant(VT_BSTR || VT_BYREF, "");
$RL->RLVersion(1, $y);
print $y;

I think something like this should work.
