C# OracleConnection exception

Hi:

I took over a C# solution from someone who has left the company.  There were a few dlls missing from the solution. I downloaded them using NuGet in order to make the projects compiled and built. However, when I run one of the projects, an exception is thrown:
Error Message:
The type initializer for 'Oracle.DataAccess.Client.OracleConnection' threw an exception.      
InnerException:
"The provider is not compatible with the version of Oracle client"

Can anyone please point me to a direction of how to resolve this issue?
I am running my code using VS2012 targeting C# 4.0 and x86 plateform.
My machine is Windows 7 64-bit.
The version of Oracle.DataAccess.dll I downloaded is x86 2.112.1.0.

Thanks.

use the 32bit for Entity framework

If you get the exception 'The provider is not compatible with the version of Oracle client', don't stress, simply retrace your steps and make sure you get ALL those DLL's from the same ODP.Net / ODAC distribution to avoid version number conflicts, and put them all in the same folder as your EXE (or, in the Bin folder if its an Asp.Net application, then try restarting IIS). If you download a newer version of ODP.Net, the jar files that enclose the dll's may have moved, so you'll have to manually search through them all, don't worry it won't take *too* long!
