Do you mean Wire.h? Filename case matters! I suspect this was your real problem.

The Wire library uses low level, architecture specific code. For this reason, each hardware package bundles its own version of the Wire library. The Wire library is already installed on your computer so there is no need for you to download it from anywhere. If you were to do so, you would need to make sure you were getting the right version of the Wire library for the board you're compiling for. For example, you would have no luck using the Arduino AVR Boards Wire library with an Arduino Zero (which is SAMD architecture).
