It will most likely fail to install, so try the manual method (this is for the 64bit version):
1. Open Payloads -> AdobeCameraRaw8.0All-x64-100913200318 -> Assets1_1.zip,
2. Extract the file "1002", and rename it to "Camera Raw.8bi"
3. For Photoshop CS6: Copy "Camera Raw.8bi" to C:\Program Files\Common Files\Adobe\Plug-Ins\CS6\File Formats
If you're using Photoshop CC, the path is:
"C:\Program Files\Common Files\Adobe\Plug-Ins\CC\File Formats\"
(overwrite the existing file).
4. That's it, cheers!
