Version number shown on SOS page for this is same as the one I got from another giveaway site on 1/21/2018. So I didn’t try to download the program today, can’t say anything about all the problems in the other comments.
What I can say is that it works great on my Win 10/64 system. It can take a while to process a picture but the results are often worth the wait. This program does things I haven’t seen in any other program, very nice! It transforms your picture into recognizable styles from well-known artists.
The description I have from my 2018 download says “Unzip the package you`ve downloaded and install the software by running Setup.exe, then press ‘Buy/settings’ and register the software with the license key below.”
That must have worked for me back then.
