I have had EQ 4, 5 & 6.
Don't use it a great deal, but it is fun & not too hard to learn if you know basic computing.
My biggest gripe is the fact that with EQ6 you can only put it on 3 computers, & then it will no longer download.
Luckily, I wasn't too fast at putting it on a computer, as both the desktop & laptop that I had at that time crashed. That would have been 2 downloads.
I put it on my replacement laptop only, - & that recently crashed! That would have been my 3 & last, - meaning that I would no longer be able to use the program I had paid $150 for.
At present it is not on either of my computers, & I am wondering if I can put it on a USB flash drive & use it from that. I seem to have become the queen of computer crashes.
My pfaff embroidery software has a usb dongle with it. You have to have the dongle inserted in order to use it. I thought that was a pest at the time, but I understand why they do this, - & now wish that EQ had gone the same route.
