Driver's SQLAllocHandle on SQL_HANDLE_ENV failed

We installed Oracle client 10.2.0.3 on a window 2003 64bit server. When I set up Oracle ODBC Driver Configuration, got the following error message in testing connection.
Unable to connect
SQL State=IM004
Driver's SQLAllocHandle on SQL_HANDLE_ENV failed

How to pass the testing of connection in ODBC configuration?
Thanks!

Did you setup the client prior to configuring the ODBC DSN?

Are you using 64-bit binaries?

Yes, I installed Oracle Client, and then set up ODBC.
And got the error message when I clicked the button "Test connection" in Oracle ODBC Driver Configuration.
