I got an error while calling a .net driver written in 4.0 version in my VEE 9.3 environment. I have installed .net 4.0. I don't understand why the VEE engine would not use .net 4.0 driver. The error message was "Not Registered". Is there a VEE configuartion file to modify in order to be able to use a newer version of VEE library than the default .net 3.5?
