ODP.NET

Hello,

I will try to make it simple :

I have a .Net program that is using Oracle.DataAccess.dll (I mean, I really use classes that are specific to that dll, if I switch to .net System.Data.OracleClient, I cannot compile anymore).
This program is executing a Package on an oracle 10G database.

My development environment is a windows 7 64 bits.
The version of the DLL is *4.112.3.0* (the 32 bit one ( ODAC 11.2 Release 4 (11.2.0.3.0) the XCopy version (http://www.oracle.com/technetwork/database/windows/downloads/utilsoft-087491.html))
My program is targeting to x86 CPU (because the users here are running XP or 7 32 bits).

My program is working fine on my development machine.

Once I copy the exe and the dll on a windows 7 32 bits, I got an exception when opening the connection to the Database.

If I install the ODAC 11.2 Release 4 (11.2.0.3.0) with Oracle Developer Tools for Visual Studio on the machine, my program works fine !

The issue is : we don't want to install that client on all the computers in the company.
We want that the program works with the embedded DLL.

I tried to register the dll in the GAC (the GAC of the .net 4 located in C:\Windows\Microsoft.NET\assembly\GAC_32 -> not working

Do you have an idea ?
For me the program should have everything he needs with the Oracle.DataAccess.dll....

Thanks in advance !
