The second combination (Windows 2008 , Visual Studio 2010 ,MQ 7) is supported in Tuxedo 11gR1PS1 (Tuxedo 184.108.40.206.0).
The first combination (Windows 7 , Visual Studio 2010 ,MQ 7) is not supported. The Tuxedo 11gR1PS1 installer for
Windows 7,VS2010 is "Client Only" (i.e. does not have any Tuxedo MQ adapter server).
What Bob meant was that Windows 7 is not considered a server platform by Microsoft, so we only support Tuxedo clients on Windows 7. Since you mentioned WebSphere MQ in your original post, I suspect Bob thought you might be using the Tuxedo MQ Adapter which is a server only related feature. You can use Tuxedo client APIs and MQ directly on Windows 7, although you obviously won't get any transaction management as that can only occur if MQ is being accessed from a Tuxedo process (client or server) that is running on a system running the Tuxedo natively, i.e., full install. Tuxedo remote clients use delegated transactions, i.e., the transaction context is only present on the Tuxedo server system the remote client is accessing. Any local transaction context on a Tuxedo client system is NOT propagated to the Tuxedo server.
I hope that made sense.
