I'm using GAUSS LIGHT 9, and because I want to buy the maxlik package I've contacted Gauss Aptech who asked me to send them the serial number of the GAUSS LIGHT 9 so that they can give me the most appropriate version of it? how can I get that number? I've downloaded gauss light 9 from http://www.aae.wisc.edu/aae637/gausscode.htm
GAUSS Light is a version of GAUSS with some limitations that is free to all students. If you are a student you should contact customer service and tell them that you would like a copy of the latest version of GAUSS Light (which is much improved compared to GAUSS 9) and that you would like to purchase Maxlik.
This is Aptech Customer Service. I am following to make sure that you were able to get Maxlik and the latest version of GAUSS Light? Please let us know if you need anything else by contacting us at: customer service
