Answer 1

Do everything suggested by ziesemer.

You may also want to remove from the registry:

HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\ keys     

HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\ODBC Drivers values

So they no longer appear in the "ODBC Drivers that are installed on your system" in ODBC Data Source Administrator
