Executable built with VS2010 is not a valid win32 application; bindump says it's a DLL

Question

I've been making a C++ program involving FFTs, and it worked fine up until I decided to use FFTW. After making the libraries from the .def files and linking them to my project, it builds successfully. When I try to run the application, however, it tells me that it is not a valid win32 application. Running dumpbin on the produced file yields:

(see edit)

Any ideas as to what the problem might be? I'd like it to go back to building as an executable file.

Edit: Full dumpbin:

Answer 1

Figured it out, if anybody else has a similar problem:

I was linking the .exp files as well as the .lib files; only linking the .lib files and placing the .dll files in the directory fixed the problem.
