Re: Scanning of 64 Bit registry

I've used this module on Server 2008 64 bit successfully (32-bit Strawberry Perl 5.8 and 5.10 and same as pp-packed executable). There is nothing to take care about. The only problem is if you are using 32-bit application and try to access keys below

HKLM\Software
[download]

this access get redirected to

HKLM\Software\Wow6432Node
[download]

Maybe you want to check http://support.microsoft.com/kb/896459 and http://support.microsoft.com/kb/305097 for further information.

First try to check which version of perl you are running then check if the keys are available in the proper registry subkey.

Update: There are some hints on the MSDN how to access the other "registry view" using VB amd WMI. It should be not such hard to rewrite it in perl. Look at this article: http://msdn.microsoft.com/en-us/library/aa393067(VS.85).aspx

Hi, Thanks for your Support... here i will give you detailed description.I am able to access keys when i am using `my @Keys_Lmachine = keys %{$RegHash{LMachine}{SOFTWARE}};` but if i change my query to `my @Keys_Lmachine = keys %{$RegHash{LMachine}{SYSTEM}};` it is returning undef may be it is because SOFTWARE is a shared subkey but not sure.... Please comment.. Regards Vikas Sharma	[reply] [d/l] [select]

Hi Vikas, this is not true. HKLM/System is shared/same but HKLM/Software/<some subkeys> is redirected or "reflected" how MS says. Please read and understand all provided links to MS knowledge base. At the moment I have no 64-bit system to check but I'm pretty sure the problem is somewhere else. I use OO-style access to the Win32::TieRegistry object like this `my $registry_obj = $Registry->Connect( $hostname, $registry_key, { Acc +ess=>'KEY_READ' } ) or do { $log->error("access to [$registry_key] on host [$hostname] f +ailed"); return; }; $registry_obj->SetOptions( SplitMultis => 0 ); $registry_obj->SetOptions( FixSzNulls => 0 ); $registry_obj->SetOptions( ArrayValues => 0 ); $registry_obj->SetOptions( DWordsToHex => 1 ); } ... foreach my $registry_subkey ( $registry_obj->SubKeyNames() ) { something; }` [download] but I don't think it makes any difference. regards willi	[reply] [d/l]
