Could not load file or assembly crdb_adoplus.dll

3055 Views

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.
