Outlook 2007 Bitness

Question

I need to get the bitness of Outlook, in 2010 it is stored in a ReqistryKey named Bitness under the path

64bit Windows:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Office\14.0\Outlook\Bitness
32bit Windows:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\14.0\Outlook\Bitness

In 2007 these Keys doesn't exist, and so I retrieve a null reference exception.
My Question is, how can I get the bitness in Outlook 2007? I need to set header, so I have to use it.

Answer 1

Outlook 2007 does not have a 64-bit version. If it's being used then it is the 32-bit version.
