Hi Marmot, Thanks for your reply.
My system is required to migrated to Win2008 X64, the Perl scripts is a part of the system, so I don't want my Perl has to keep at the 32 bit version due to this module Win32::Perms, can you please help to give a suggestion which module can replace Win32::Perms and implemented the same function(get/change a file's owner)???
