Open Korean HWP file using Word

Below is an instruction on how to open a Korean word processing HWP file using Word program. But I am not understanding how to choose HWP 5.0 or maybe it does not work. 

To install this download:

1. Download HwpConverter.exe by clicking the Download button (above) and save the file to your hard disk.
2. Run HwpConverter.exe. The files will be extracted to %Program Files%\Microsoft Office\Office15.
3. To open and edit a HWP file, open a supported Microsoft Word program, choose HWP 5.0 type in file open filter, and select a HWP file.
