Hi,

Just downloaded the zlibwapi.dll 32 bit renamed it to zlib.dll and placed it in the windows\system32 directory, however after restarting iis the csp gateway is not finding it. 

Initialization
Information: The GZIP library (ZLIB) is not present on this system. This library is used for the optional GZIP compression facility.

I will investigate further and then log a wrc call.

Regards

Gary
