I believe (and I'm just speculating) that the issue is that your application is a 32bit application.
You need to tell the compiler that it needs to be a 64bit application.
This is because a 32bit application cannot consume a 64bit dll. It is possible that a 64bit application uses a 32bit dll however.

As I said, I am speculating because of the following statements which seem to contradict each other:

"This will occur when running in 64 bit mode with the 32 bit Oracle client "

and

3.Oracle 11g release 2 (64 bit)

Firstly, try setting your projects build to x86 and see if that fixes the problem.

Hi, can you confirm which Oracle client you are running? Use tnsping to determine which Oracle client is been used. It might be that the 64 bit client is last in the path variable and the 32 bit Oracle client is been used instead.
