I am trying to connect to an Oracle server using an ODBC connection within ArcCatalog on a 64 bit machine but am getting the attached error message. I have setup the System DSN entry that I am using on the 32 bit version of the ODBC Data Sources.
With the same setup on a 32 bit machine I can connect fine which leads me to believe it must be something to do with the 64 bit machine.
Is anyone aware of any issues when trying to connect to Oracle using an ODBC connection on a 64 bit machine? Do I need to alter any settings before I attempt this or should it work as it does on 32 bit machines?
