Hello. I recently installed UE4 on windows 10 64bit and it is refusing to build any content example or project examples. Here is a screenshot of the log.
Please look into the link that NatalyaK provided. If that does not work, please reply back with a text document of your full output error logs for this project. Also include whether or not you’re on Unreal Engine 4.10.2, or if you’re using a source version of the engine.
