I’m unsure why people seem to be having activation problems. One thing I can suggest from past experience is that if you are using a VPN, turn it off to register as that can sometimes interfere.
I just downloaded and installed this to a thumb drive and it registered without issue. I have not tried the program yet, no time today, so cannot review but it came at a good time for me as I had a hard drive crash so I will be trying it soon.
Many thanks to iBeesoft and SOS for this!
