Hi, I'm looking to make a connection from a 64 bit Win 7 PC (MS Access) to an Informix database on Unix. We were successful on XP machines with an older ODBC driver. I downloaded and installed both the 32bit and 64bit Client SDK Developer Edition for Windows from IBM with no success. The 64bit installs ok but gives an architecture mismatch error and the 32bit driver installs an open admin tool that does not help. Any suggestions would be appreciated.
