Unable to load the Managed C++ dll into C# Dll

I have a C# application which is built with platform target as ANY CPU. It references a managed C++ application which is built with the platform target as Win32. However the loading of the C++ dll fails at runtime with the following error. "Could not load file or assembly 'abc_Debug, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. Attempt to access invalid address. (Exception from HRESULT: 0x800701E7)"

Can anyone give me some pointers as to what could be wrong?

If you are running the application at a x64 architecture then your app is starting as x64 and then it can't load the c++ reference. You cannot build an application as AnyCpu if you don't have all the dependences available for AnyCpu, otherwise set x86 as the target.
