Hello
You want to install the preinstalled DVD player software? This tool isn’t downloadable for Windows 7 64bit and can only be installed from recovery disk with the whole recovery image.
But why installing a DVD player? Just use VLC media player that can play a lot of more video and audio files. It’s nice freeware tools and makes DVD player software unnecessary. You can download it here:
