  Paid for Epson Stylus Color 900 service program and afterwards tried to download program from link. Link would only download a HTML file, and not an executable. Left a message from 2manuals to assist me. This is too damn difficult. Why can the link not just download the executable? ============= Just checked - it works fine. Maybe there were server problem at that moment. You have been sent direct link. John.
