Try selecting Force 32 Bit option in Expression Editor below the ODBC list box.

Hope it helps you.
That is a great thread! Thank you very much Jagan.
So your trick has fixed some of the models, but there is a small percentage of models that are run on a different server to where the database reside.
I have copied the jadodbc.dll files also where QlikView runs from, but I can't still see the jade driver on the list when I open the ODBC Administrator 64 bit from QlikView.
Thank you Jagan.
