Missing locale data in Windows Informix Client Tools SDK ODBC install?

Hi all

I'm attempting to use an ODBC connection from a Windows 2012R2 server  to an Informix server using the clientsdk.4.10.TC6DE.WIN install.

However, when I try to test my ODBC connection, I get the following error:

'Test connection was NOT successful.[Informix][Informix ODBC Driver][Informix]Unable to load locale categories.'

If the locale data was correctly installed, where should it be? I don't see a gls folder in my INFORMIXDIR.

setnet32 seems to have the correct locale values, and matches what is in the registry.

Does anyone have any ideas on how I might resolve this issue? Am I installing the correct driver? I'm using clientsdk.4.10.TC4DE.WIN on Windows Server 2008 machines without any problems.

I want to use the driver with SSIS so I'm installing the 32 bit version.

Thanks in advance.
