The D in the library name signifies that it's a debug-mode runtime for VC 2008. Ensure that you haven't made any changes to the debug and release settings of your project, particularly the run-time /MDd in the "code generation" section.

This error would appear when you run your code, not when you build it. Rebuild the project.
