I am trying to copy registry permissions from one key to another (and eventually to many others). key1 has full read/write permission for administrator and read permission for users, but key2 only has read permission for administrator (although I can change permission by manually running regedit) and no permission for users. This script doesn't seem to do anything (it prints the values, but does not change security that I can see). I also tried setting full read/write permission on key2 for the administrator group in regedit (though the other keys I want to change don't have it), but user permissions don't get added:

use strict;
use warnings;

use Win32::TieRegistry qw( Delimiter / KEY_READ KEY_WRITE );
use Win32 qw(
  DACL_SECURITY_INFORMATION
  SACL_SECURITY_INFORMATION
);


my $path = 'LMachine/Software/Classes';
my $key1 = 'opendocument.WriterDocument.1';
my $key2 = 'opendocument.WriterGlobalDocument.1';

my $r = $Registry->{"$path/$key1"};
print $r->{"/"},"\n";

my $sec;
$r->RegGetKeySecurity( DACL_SECURITY_INFORMATION, $sec, [] );

# Only have read access on this - but can manually run regedit
# and change permissions
my $r2 = $Registry->Open("$path/$key2", {Access => KEY_READ(), Delimit
+er=>"/"});
#my $r2 = $Registry->{"$path/$key2"};
print $r2->{"/"},"\n";
$r2->RegSetKeySecurity( DACL_SECURITY_INFORMATION, $sec );

Update: Just to mention where I'm trying to go with this, there's a bug when you upgrade OpenOffice which causes insufficient permissions on these keys for users (works ok for Admin accounts), so I'd like to fix all permissions for keys in this path with keys or values that start with 'openoffice.' or 'soffice.'.
