Oracle provider Oracle.DataAccess not find. Version - ODAC 4.112.2.0

Question

Hello,
Please to help me!!!!...??? I don’t know more what to do.
I have an application ASP.NET, C# with access to the database Oracle by ODAC.
It was worked without problem on the platform x86. I have tried to put it on the server Windows 2008 R2 without of the success.
Than on the other PC I have installed:
-Windows 7 platform 64 bit.
-ODAC 11.2 Release 3 (11.2.0.2.1) with Oracle Developer Tools for Visual Studio and I have put this -path in the system path
-Visual Studio 10
-Framework 2 (v2.0.50727) and 4 (v4.0.30319)
- I have configured IIS server two “Pools Classic” for Framework 2 and 4
In the debugging by Visual Studio 10 it is working with Framefork 4 and with use of Framework 3.5 too, by using the assembly (Version=2.112.2.0 or Version=4.112.2.0):
<add assembly="Oracle.DataAccess, Version=2.112.2.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />
In the web.config.
But it’s problem when I try to start it directly from IIS (it’s not changed if I use “batch build” AnyCPU, x86 or x64):

When I look to GAC, I don’t know exactly all of the links, but I think that all is in order :

Hi all,
I have find the option to “Create new project platform”. It was the line
“<identity impersonate="true"/>»
in the web.config file, who have blocked this option.
But the problem is that it’s nothing to bee changed.
In the Visual studio with debugging it’s all of the version who work
X64, x86, Any CPU and all of this versions with Framework 3.5 or 4.
But when I try to run it, directly by IIS it’s not working.
The same error for:
<add assembly="Oracle.DataAccess, Version=2.112.2.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />
As for
<add assembly="Oracle.DataAccess, Version=4.112.2.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />
Please anybody to help my.
I really don’t know what to do!!!
