Note The 64-bit versions of Microsoft Host Integration Server 2006 and Microsoft Host Integration Server 2009 only install the 64-bit versions of the Host Integration Server SNA APIs, so legacy 32-bit SNA applications cannot run off these systems either.

Therefore, legacy 32-bit SNA applications cannot run on 64-bit versions of Host Integration Server systems or Host Integration Server Client systems. This includes Advanced Program-to-Program Communications (APPC), Common Programming Interface for Communications (CPI-C), Request Unit Interface (RUI), Session Level Interface (SLI), and 3270 Emulator Interface Specification (EIS). When you install Host Integration Server 2010 on a 64-bit version of Windows, only the 64-bit versions of the Host Integration Server SNA APIs are installed.

This article describes a software update that enables 32-bit Systems Network Architecture (SNA) applications to run on 64-bit versions of Microsoft Host Integration Server 2010. Microsoft Host Integration Server 2010 More.
