When I download the Open Client from the download center, it installs the 10.2B driver version 5.30.00.109 PGOE1023.DLL.
I would like to use this ODBC version: 10.2BSP8 7.10.02.48 PGOE27.DLL
Installing the service pack fails as it complains about the DLC variable. I only have the open client installed.
How can I get the ODBC version I need ?
Assuming that you have 10.2B08 on another Windows machine, try option 1a/b of the following KB article:
000021257, "Is it possible to use an ODBC driver without a full installation?"
Option #2 would not provide the later driver version; option #3 does not apply.
