SysWOW64 is just the equivalent of the system32 folder for 32-bit system apps, dlls, etc. system32 is where the 64-bit versions of system apps, dlls, etc are installed. Yes, the naming seems screwed up, but that's the way it is.

From: Nobody on 1 Feb 2010 12:35 Thanks everyone for the quick responses. I am using SetWindowExtEx() API function, which requires that I use a 64-Bit DLL if I want to hook a 64-Bit process(This is documented in MSDN). It's one of the few differences between 32 and 64 Bit OS'es. I have one last question: Does the shortcut in the Start Menu start the 32 or the 64 bit version? Thank you
