About 32-bit registry keys on a 64-bit Windows client

On 64-bit Windows systems, the Windows Registry action can check for registry keys in the 64-bit registry or the 32-bit registry. The following registry root key names are supported:
An HKEY value that includes the bit value 32 can provide a 32-bit view of a 64-bit registry. This is the perspective used by 32-bit applications running on a 64-bit operating system. An HKEY value that includes the bit value 64 can provide a 64-bit view of the registry. This is the perspective used by native 64-bit applications.
Keys without a bit value specified use the default Windows registry redirectors, as specified by Microsoft. On a 32-bit Windows system, the number of bits specified in a registry key name is ignored.
