Are you on a 64-bit operating system?  Are you entirely sure that the
Bloomberg Desktop API v3 a 32-bit service?  Remember that you can ONLY
call a 32-bit in-process server from a 32-bit application, and a 64-bit
server from a 64-bit application.

You could check in the registry.  If you find an entry under
then you have a 64-bit version.  If you find an entry under
then you have a 32-bit version.
