Not to sound like a broken record, but are you sure this isn't the default 64-bit ODBC administrator. They have two different ODBC Administrator, and stores the 64-bit/32-bit drivers in separate locations, and if my memory serves, 64-bit ODBC administrator is used by default. Since there's no 64-bit drivers for Access, it won't work, so we need to manually select 32-bit ODBC (again, going by memory, it'd be named ODBC (x86) Administrator then we can use driver from there.
