Error importing assimp library

I need to convert a .dae file to .obj for a work I'm doing in C#. I only found this library that seems to work but when I start the program it crashes. I imported it going to Project > Add Reference and then choosing the AssimpNet.dll file in assimp-net-master\AssimpNet\bin\Net20-Debug. It gives me this error:

Assimp.AssimpException occurred HResult=0x80131500 Message=Error loading unmanaged library from path: Assimp32.dll, see inner exception for details. The specified module could not be found. (Exception from HRESULT: 0x8007007E)

This is my code:

    private void button1_Click(object sender, EventArgs e)
    {
        AssimpContext context = new AssimpContext();
        String colladaPath = "lamp.dae";
        Scene ducky = context.ImportFile(colladaPath);
        ExportDataBlob blob = context.ExportToBlob(ducky, "obj");
    }
