FIX: A 32-bit application using the SLI interface fails to load a custom DLL used to process a BIND request

Applies to: Host Integration Server 2016


Assume that a 32-bit version of wsli3270.dll isloaded on behalf of a third-party software to locate a specific Dynamic Link Library (DLL) . However, the C:\Program Files\Microsoft Host Integration Server\SysWOW64 folder is only looked upand did not search the path to locate the custom DLL. Additionally, when you call SLI_OPEN, the application may fail.


The SLI code is using the HISLoadLibraryfunction instead of LoadLibrary when trying to find a user DLL.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. 


This issue is fixed in the following cumulative update for Host Integration Server:
