Had no doubt on that, at all. Actually I can say I knew it. I'm not John Snow, you know?
Kidding aside ─ now I am serious ─ there is clearly something wrong with the zipped file or with GoFile download that comes as corrupted, because... I have all the needed hard drive space, wi-fi has been restarted and goes fine with no interruption of sort and I've downloaded the file again. Still same problem happening, as this screenshot right below proves beyond any reasonable doubt.
Now... I'm not whining and I'm not blaming the generous uploader who shared the file with us. I'm just pointing out a problem I never had like this, because usually all I needed was to free some space and restart the computer like I did with any attempt made today.
I'm not an expert so I'll let the experts talk, if they want to say anything about this problem and if they have a solution eventually, aside the solutions I'll try by myself.
Now... enough with indulging into my most
seriousness driven mood, I'm back to my finest playtime driven mood!
