Supporting Oracle Client, ODAC, and ODBC Installs on 32- and 64-bit Windows
My first thought was to install the latest 32-bit version of ODAC 11.2.0.2.1 on both the 32-bit and 64-bit workstations. This allows us to support existing 32-bit applications (no we can't upgrade them all yet) with the latest ODP.Net and its support for .Net Frameworks 4.0. This version of ODAC also comes with the 32-bit ODBC drivers.
