Registry Keys

When 32-bit applications such as the PE hub are installed on 64-bit machines, any associated registry keys are created in their own ‘32-bit’ subkey. So while registry values for the Exchange 2007 and 2010 server agents are created in the \SOFTWARE\ComputerAssociates subkey, registry values for the PE hub are created in the \SOFTWARE\Wow6432Node\ComputerAssociates subkey.

CA DLP registry keys, 64-bit machines

1 Exchange 2007 server agent registry key.

2 PE hub registry key.

Note: Why ‘WOW64’? On a 64-bit Windows operating system, there is an emulation of a 32-bit operating system called ‘Windows on Windows 64’, or WOW64.
