I used GAUSS among other software in grad school. I have some startup money to spend on software. If Aptech/GAUSS is still a viable company, I would like to purchase a license. But I don't want to buy a software that would be out of business in a year or two (that's my gut feeling because I saw fewer and fewer people using it), especially since the license is tied to a computer and I would not be able to transfer to a new computer should the company be out of business. Do people still use GAUSS?
