I was able to connect to it with setting up a DSN from "ODBC Data Sources" from control panel, so I would suspect it's a driver issue.
Did you uninstall the 32-bit office? I'm not sure the 64-bit driver will install directly over without the 32-bit being uninstalled first
Intel Xeon E5630@2.53Ghz
NVIDA Quadro NVS420 Dual Monitor
12GB Ram / Win7 Professional 64bit SP1
Our IT guy uninstalled the 32bit suite and installed the 64bit Access 2010 (stand alone) and the 64bit Office Home and Business 2010 suite. If you connected it must be something I am doing wrong on my end, I am also assuming the insatll went correctly.
