I need help installing an updated version.

I tried to install from official site but a trojan was detected by my antivirus so I stopped installing.

Then I tried from another site, it was version 04
This one works but my families are not loaded.
I tried to put only the new .exe in the old folder, worked but families not loaded neither.
I suppose I have to put the "family files" into the new folder but I am not able to find it.


I am excited playing this game and my little boy who is 6 too !!
He is trying to learn english when reading status and actions, so funny, because he just learnt to read french (we are french)

I hope you can help me !
thank you
