The "win32" refers to the win32 API in Windows, and has little to do
with being 32 bit or 64 bit. You must use the 32 bit version of the
library for 32 bit apps, and 64 bit version for 64 bit apps.

I doubt that is going to work. Again, you cannot share handles across
applications on any sane O/S. You can share handles across threads, but
not processes. Create a pipe and send the data to/from that.
