You need to use the 32-bit ODBC administrator to create your data source. It is called odbcad32.exe and is in the C:\windows\system32 directory I think. You mayneed to search around for it.
Thank you for the reply. I found the 32 bit access driver and I was able to build an access connection in SQLDeveloper. Now I have other issues where certain screens do not populate properly – the “schemas available to migrate” screen and the “available database connection” screens. I think it is a result of mixing 32 bit with 64 bit. I will open a new thread with this issue.
