MySQL ODBC DSN: Invalid Attribute string

Today, I found out a Server running Windows Server 2008 R2 with 64 bits server getting error of Invalid Attribute String error when click on the ODBC Manager.

Actually, I still suspected that the server did not install the current 64 bits ODBC but applied 32 bits ODBC DSN only.

After checking from this case, end up I have tried to reinstall the ODBC directly from MySQL Connector page as below.
http://dev.mysql.com/downloads/connector/odbc/5.1.html

With this step, it fixed the problem automatically and all ODBC work without any issue.
