Verify that your Microsoft Access (MA) driver is present on your operating system. This can be done by doing one of the the following:
Check the system and user temp folders to make sure that there is no issue with rights. To do this click here.
Check the following registry entry for the reg key "Microsoft Access Driver (*.mdb)": HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI
Verify the MA driver (*.mdb) is present on that operating system. For Vista 32 bit open c:\windows\system32\odbcad32.exe. For Vista 64 bit open c:\windows\syswow64\odbcad32.exe. Run odbcad32.exe and verify if there is "Microsoft Access Driver (*.mdb)".
