The Google Test project (gtest.vcproj) has the Runtime Library option set to /MT (use multi-threaded static libraries, /MTd for debug). If your project uses something else, for example /MD (use multi-threaded DLLs, /MDd for debug), you need to change the setting in the Google Test project to match your project's.
To update this setting open the project properties in the Visual Studio IDE then select the branch Configuration Properties | C/C++ | Code Generation and change the option "Runtime Library".

== I define my tests in a library (.lib) and Google Test doesn't run them. ==
This happens when you use Microsoft Visual C++ and define your main() function in your .exe file and define your tests in a static (.lib) library. MSVC linker sees that your main() function doesn't use any symbols defined in the library and throws the library out. To force the linker keep you library, use the /OPT:NOREF linker option. If you use MSVC++ IDE, go to your .exe project properties/Configuration Properties/Linker/Optimization and set References setting to "Keep Unreferenced Data (/OPT:NOREF)".
