Could not load file or assembly crdb_adoplus.dll

Question

Hello everyone!..
I am having a really annoying problem, in my code when I try to set de data source to the report the following error appears:
Could not load file or assembly 'file:///C:\Program Files (x86)\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win32_x86\dotnet1\crdb_adoplus.dll' or one of its dependencies. The system cannot find the file specified.
I am running .NET Framework 4 running in VS2012 to X86 and I have installed the CRforVS_13_0_8, although just in case I installed all the version from the CRforVS_13_0_5 to the CRforVS_13_0_8.
Also I have found in many sites that adding the following lines to the app.config seems to fix the problem, but in my case doesn't work:
    <startup useLegacyV2RuntimeActivationPolicy="true">
         <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
     </startup>
Part of my code is this, just in case:
using (ReportDocument report = new ReportDocument())
       try
       // carga el reporte desde su ubicación configurada
                 report.Load(pathReporte);
                 report.SetDataSource(data);
and the dlls I have referenced are this ones:
CrystalDecisions.CrystalReports.Engine
CrystalDecisions.ReportSource
CrystalDecisions.Shared
Thanks very much for your help in advance.

Hi Javier
Two things to do:
1) Read this blog re. troubleshooting issues with CR and datasets (the error is different, but try anyhow)
2) Use Process Monitor and see what is happening when your process is attempting to load the crdb_adoplus.dll
