Peter,
Have you downloaded, checked the files? It is implied that there are 19 files in the download, 5 of which are the .pdf manuals you are looking for, check the .jpeg files.
Look at the 2nd image, and all of them, the product key is on one of the images, and it tells you that it is for Win95 or WinNT (my choice would be NT).
