FIX: Event ID 627 when you try to run a 32-bit APPC application on a 64-bit version of Host Integration Server 2013

View products that this article applies to.

Symptoms

You try to run a 32-bit Advanced Program-to-Program Communications (APPC) application on a server that's running Microsoft Host Integration Server 2013. If the server is running a 64-bit version of Host Integration Server 2013, the application does not run, and the following event may be logged in the Application log:

Event ID: 627
Source: SNA Server
Description:
Internal message routing error: process id pid, mhtype 1, msgtype 1

Cause

This problem occurs because the APPC application's instance of the Host Integration Server client/server interface (Snadmod.dll) tries to locate the Host Integration Server security groups in the following registry locations:

HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\Host Integration Server\AdminSecurityGroup
HKEY_LOCAL_MACHINE \Software\Wow6432Node\Microsoft\Host Integration Server\RuntimeSecurityGroup

However, these registry keys do not exist on 64-bit versions of Host Integration Server. Therefore, no access control lists (ACLs) are set on the semaphore object, and this causes the application failure.
