RE: "fake" hive in the registry on 64 bit windows

Joel,

Thank you. Not only did this explain what was happening it gave a solution without anything being added.
Trying to create a script to gather the registry information for a program that happens to be 32 bit and ships with a basic Perl for a Perl API, I figured this would be a great way to remove human error, unfortunately I did not expect the caveat you explained and resolved quite nicely.

Thank you again.

And thanks to everyone whom replied. The options of extra items was something I was going to bring up and look into due to the need to verify our registry section correctly.

Sincerely,

I'm not certain if this is your problem, but if you are running an x86 copy of Perl on an x64 system, and you are using backticks for execution, Windows filesystem redirection will kick in and actually execute %windir%\SysWOW64\reg.exe.  The x86 version of reg.exe is different, and may (purposefully) not have access to the 64bit registry.

Try executing $ENV{SYSTEMROOT} . '\\SysNative\\reg.exe' instead.  You won't see the SysNative directory from the standard (x64) command prompt, but it will exist from within an x86 shell with filesystem redirection.

Subject: "fake" hive in the registry on 64 bit windows

Dear Perl Gurus,

I have an issue with reading registries in Perl. I know there is a ppm for this, but requirements prohibit the use of this package. I am instead using "reg"
I have posted on the Active State Forums, yet they seem infrequently used., so I am reposting here.

In the attached sample script I get an extra copy of the 32 bit hive in the 64 bit section. This is even after creating a fake 64 bit section that has one key called "isThisReal" with value "Do You See Me?" as a Reg_SZ

Instead I get the attached output.
Any help on figuring out how to get the real 64 bit hive section would be GREATLY appreciated.

There should be an attachment of a zip file containing the test script and its output.

(Notice: This is a REGISTRY QUERYING SCRIPT. if you are uncomfortable touching your windows registry, please do not execute.)

What i tried for testing was to run the commands OUTSIDE of perl in the command shell and i get the correct output there.

This is being developed to gather information on server machines so i've been using Windows 2008 R2.

I'm sure it is me missing something as this is not something i would expect to be uncommon, so i apologize in advance if this seems stupidly simple. Google and other search engines have not helped as i have not found anything particular to this.

Again, thank you in advance for any assistance.
