I was looking to make some space on my laptop, which is running windows XP, and came across this file. what surprised me was its size, approx 1.6G. It also says that I used it frequently; however, the last time was about a year ago. I checked with a co-worker who has the same laptop and he also has it but it's about 0.8M. I also have MathCad installed and it seems to have something to do with licensing. Can this program be deleted?
