When users are trying to execute some reports in Strategy, they may receive message that “QueryEngine encountered error: Execute Query failed” and “You are not licensed to use this ODBC driver with the DataDirect ODBC Driver Manager under the license you have purchased” information as shown below:

Additionally, in the DSSErrors log users can find exactly the same error:
Error type: Odbc error. Odbc operation attempted: SQLExecDirect. [HY000:0: on HSTMT] [DataDirect][ODBC lib] You are not licensed to use this ODBC driver with the DataDirect ODBC Driver Manager under the license you have purchased. You can order a license by calling DataDirect Technologies at 800-876-3101 in North America and +44 (0) 1753-218 930 elsewhere. Thank you for your cooperation..

Line that starts with ‘QEWSD’ under [ODBC] section in odbc.ini file should be removed. The good practice is to change odbc.ini file to read-only mode to ensure that it is no longer re-written.
