Updated ODBC32.DLL File

I'm running into problems with some routines in a VB6 app tied into a SQL Server 7 database. Basically, it appears my ODBC32.DLL file needs to be updated. I currently have Ver 3.520.4403.2 and need to be at 3.70.0623. I am using MDAC 2.5.

How should I update my file? Should I update to MDAC 2.6? Can I find the file and download it without creating problems?

Anyone???

I just updated to MDAC 2.6 and no change in the ODBC32.DLL version. How in the HELL do I get a new version?????
