AfAOS 4.7 has an included installer, but I have never gotten it to work right.
The way I got things to work was to try running the installer, which copies some files over (but not all), then go to the guide and look in the section called Manual install, and follow those instructions. I'd also go through and make sure that the files in the subfolders are copied to the corresponding folders on the HDD. After a restart, then you should be able to run the two prefs programs (one is for the window frames, the other is to install TTF fonts for use by the Fonts prefs program).
