I have downloaded the 3.1 complete installer from the site and tried to install it on a Intell P4 1.2ghz running Windows 2000 pro Service Pac4. The computer does not have an internet connection. I followed all of the instructions and installed sp4, direct x 9 and wmp 10, then wmp 9. The first failure came when directx was not recognized. I had to reinstall direct x again, this time from the microsoft download. The next failure came while looking for codecs. Back to the ms sight to download WM9Codecs9x.exe. Once again failure at the same spot. Does anyone have a full list of codecs needed to make this software install? And, is it worth all the work? Thanks, JD
