ODBC driver

I am having trouble connecting to an Oracle DB via MS Access.

Windows 7 64 bit
Office 2010 32 bit
ODAC 11.2 Release 5 32 bit

SQLPlus connects to db using TNSNames

When I run 32 bit ODBC (C:\Windows\System32\odbcad32.exe) no Oracle driver available.

I previously installed ODAC 11.2 Release 5 (11.2.0.3.20) Xcopy for Windows x64 and I have an Oracle driver driver available via 64 bit ODBC (c:\windows\syswow64\odbcad32.exe) but the 32 bit Access cannot use the 64 bit driver.

Help anyone? I am going round and round in circles!

Pretty please ;)
