It's been a while since I worked Win64, but I'll have a go:

Win64 contains two seperate registry: one for 32 bit and one for 64 bit for
some of the COM specific keys

For instance, HKCR/CLSID entries and HKCR/Interface entries

But for HKCR/TypeLib there is but one shared entry for both Win32 and Win64
(but the binary typelib, if different, will get separate subkeys)

Yes, you will need 64 bit specific binary for the proxy/stubs. Just build
and register them along with your 32 bit ps
