I only get some "subkeys" listed but i cant read or store it in the needed section.

There are two registries (more or less), one for 32-bit apps, and one for 64-bit apps. This explains a bit.

btw, replace

use Win32::TieRegistry( Delimiter => '#', ArrayValues => 0);
my $pound = $Registry->Delimiter("/");
[download]

with

use Win32::TieRegistry Delimiter => '/', ArrayValues => 0;
[download]

I tried the following, but honestly i dont understand much/or nearly nothing of it.
This is an example which i tried to modify
Just how to read a simple value like:
"NoTrack"=dword:00000001
under: HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Common\General


use Win32::TieRegistry( Delimiter=>"#", ArrayValues=>0 );
  $pound= $Registry->Delimiter("/");
  $targetKey= $Registry->{"HKEY_CURRENT_USER/Software/Microsoft/Office
+/12.0/Common/"}
    or  die "Can't read the key: $^E\n";
  $data= $key->{"/General"}
    or  die "Can't read the key: value: $^E\n";
  
  foreach $entry (  keys(%$targetKey)  ) {
      ...
  }
  foreach $subKey (  $targetKey->SubKeyNames  ) {
      ...
  }
  $targetKey->AllowSave( 1 );
  $targetKey->RegSaveKey( "C:/TEMP/testReg", [] );

Error message:
Cant read the key: value: handle is invalid

How do i read a single value from a hash/array? or whatever this is stored when read into the Perl Code in?
Any help welcome

I don't see a .../12.0/Common/General in my registry: I see .../16.0/Common/General, and .../14.0/Common/General, but .../12.0/Common (which does exist in mine) doesn't have a General subkey.

I think you're getting confused about subkeys vs. values. You have placed the 'general' subkey in a variable called $data. In the Win32::TieRegistry examples,$data holds a value, not a subkey.

The error you are getting seems to indicate that HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Common\General does not exist. Since it doesn't exist in my registry, that doesn't surprise me.

I have built up an SSCCE which uses the 16.0 version, and looks at a value in there (since I don't have the 12.0 'General' subkey)

#!perl
use warnings;
use strict;
use Data::Dumper;

use Win32::TieRegistry( Delimiter => '#', ArrayValues => 0);
my $pound = $Registry->Delimiter("/");
my $targetKey = $Registry->{"HKEY_CURRENT_USER/Software/Microsoft/Offi
+ce/16.0/Common"}
    or  die "Can't read the 'Common' key: $^E\n";
print STDERR "targetKey = '$targetKey'\n";       # this is the one you
+ called "data" before.  It's not data, it's another key
my $generalKey = $targetKey->{"General"}    # thhis is another subkey
    or  die "Can't read the 'General' subkey: $^E\n";
print STDERR "generalKey = '$generalKey'\n";       # this is the one y
+ou called "data" before.  It's not data, it's another key
print STDERR Dumper $generalKey;
# here, you can access actual values from the key, with or without a p
+refixed slash
my $data    = $generalKey->{'/Authorized'} // '<undef>';
printf STDERR qq("%s" => >>%s<<\n), '/Authorized', $data;
my $noslash = $generalKey->{'Authorized'} // '<undef>';
printf STDERR qq("%s" => >>%s<<\n), 'Authorized', $noslash;
my $dne     = $generalKey->{'DoesNotExist'} // '<undef>';
printf STDERR qq("%s" => >>%s<<\n), 'DoesNotExist', $dne;

I get a different error message than you got... but since you omitted code, who knows what else is different. Try my example, and see what you get. If it works the same, then you can try to tweak the code to make it do what you want.

Hello
Thanks for your reply. I think i am not affected by this since the changes are only under HKCU?
and not HKLM?
