[MonetDB-users] ODBC Error

Greetings MonetDB developers! I'm preparing MonetDB for an application, and I got the current error from the ODBC: [MonetDB][ODBC Driver 11.5.9]Cannot return the number of output columns. Query must be executed first. I'm using Windows 7 Ultimate 64bits with both ODBC x86 and x64, but the system and also the Microsoft Excel only find the x86 driver. How can I overcome this? Thank you very much.
