You need to add version.lib to your project's linker options.
You can't just output lpData. You MUST access the information using
VerQueryValue() as the documentation states. You are accessing the
resource directory of the NE/PE file format. This isn't just something
you can simply write out using cout. You need to walk the potential
tree of information (this is potentially a multilingual resource).
