Interestingly, v2 is only for home users at this time.
I discovered this earlier when I tried updating the version on my work PC and came across this page.
The business version (v1.75) looks identical to the consumer version. From what I can see, there is no visual difference between it and what I recall on the v1.75 consumer version. This probably explains why there are quite a lot of requests on their forum asking when the registration is due to renewal or even how to tell if a lifetime license is in use, as even the registration info screen doesn't look any different despite business licenses being an annual subscription per PC.
