Sounds like you do not have Oracle properly installed or you are referring to the wrong version. Hard to tell when you don't share any code or config with us.

Try re-installing or there are variety of other possible solutions on this link Could not load file or assembly 'Oracle.DataAccess' or one of its dependencies.[^]
or this one Could not load file or assembly xxx or one of its dependencies. An attempt was made to load a program with an incorrect format. - Stack Overflow[^]

There are similar problems resolved on the links I provided.
If you want to comment on a post do not post your comment as a solution. Not only will you get downvoted but you will discourage other members from helping - they will see that this post apparently has 2 solutions and move on to look at someone else's problem. I suggest you remove this.
