.NET application crashing on Windows 7 64 bit

I have made an application and made the setup installer using Visual Studio 2010 and .NET Framework 3.5.

In Visual Studio 2010 I have selected "Any CPU" as platform, so it can run on both 64-bit an开发者_C百科d 32-bit Windows 7 OSes.

When I am installing it on Windows 7 64-bit, it gets installed successfully, but when I tried to open the application it is giving me the following dump:

System.BadImageFormatException means that you tried to reference a 32-bit dll from a 64-bit assembly (or the other way around). You can't mix and match stuff like this. If you need to reference 32-bit dll's, make you application 32-bit, not "Any CPU".
