MQ 6 on Windows 64 bit operating systems

So, is there such thing as WMQ 64 bit on 64 bit Windows platform?

I discovered that there is no such thing.
WMQ 6 on windows is great 32 bit queueing system that supports 64 bit windows platforms.
This issue doesn't exist on Linux/unix systems.

If you developing .Net application for 64 bit systems you should compile it as an x86 program and not 64 bit, because WMQ 6.0 doesn't support 64 bit and you will get several unexpected errors while compilation/ running of the program.

go to this link http://publib.boulder.ibm.com/infocenter/wmqv6/v6r0/index.jsp and search for "installing on 64-bit windows operating systems" for more details.
