Nope... Today with their Backupper giveaway AOMEI seems to have goofed -- trying to be charitable, assuming they didn't change their mind about the giveaway -- since it registers showing one day left before it expires. To be certain it wasn't something left over from a previous AOMEI app, I tried it in my Win7 32-bit VM, which hadn't ever seen anything from AOMEI, getting the same result. AOMEI is apparently trying to tighten up their DRM. Their last giveaway, of their Partition Assistant, unregistered for me -- trying to be charitable at that time I attributed it to my changing the CPU in this PC [no other apps, not even Win10 complained]. And an older version of the same app remained registered. Hopefully AOMEI will try again with another giveaway.
I've only ever installed Backupper in a couple of VMs, where I've played with it a time or two, but never found a reason to actually use it beyond that -- though they each have their eccentricities, Macrium Reflect & Paragon just do more, better. That's not saying anything bad about Backupper -- just that other developers have gone a bit further.
