I'm sorry to hear your friend is having trouble! :( The only thing I can think of is that when that "access denied" message appears while unzipping, it missed some files. Could I maybe have a screencap of the inside of that "DatingStart" folder?
I would recommend trying to right-click the unzipped folder and unzipping without using WinRAR, too.
They can also feel free to email me via derpychocho [at] gmail.com. I'm sorry if my replies will be rather slow! But I'll do what I can to help! :)
