SAP Crystal Reports for Visual Studio 2012 - Could not load file or assembly

Hello everyone.

I'm working with Visual Studio 2012. I'm working in a XBAP Project (WPF Browser App.)

When i try to load the report in the application, Visual Studio gives me this message:

"Could not load file or assembly 'file:///C:\Program Files(x86)\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XL 4.0\win32_x86\dotnet1\crdb_adoplus.dll' or one of its dependencies".

In the Properties Project, the NET Framework version is .NET Framework 4.5.

Looking for in internet, i read i must add this code in App.config:

<startup useLegacyV2RuntimeActivationPolicy="true">

<supportedRuntime version="v4.0"/>

</startup>

But i could not find the App.config file. So, i changed the .NET Framework version to .NET Framework 4.0 and then i could find the App.config file in the Solution Explorer.

When i open the file, i read this:

<startup>

<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>

</startup>

And, this part i don't understand well, I must add or REPLACE.

I tried with:

<startup>

<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>

</startup>

<startup useLegacyV2RuntimeActivationPolicy="true">

<supportedRuntime version="v4.0"/>

</startup>

and with,

<startup useLegacyV2RuntimeActivationPolicy="true">

<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>

<supportedRuntime version="v4.0"/>

</startup>

but i can't solve the problem.

Please, give me some guide to solve it.

Thank you!
