Detect whether Office is 32bit or 64bit via the registry

Question

Now that Office also comes in a 64bit install, where in the registry do you find out if the version of Office installed is 32bit or 64bit?

Answer 1

@clatonh: this is the path of the registry on my PC: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\14.0\Registration{90140000-002A-0000-1000-0000000FF1CE} and it's definitely a 32-bit-installation on a 64-bit OS.
