"Error writing to file" [SOLVED]

Hi! 

(This might be in the wrong place, if it is, feel free to move it)
 
I have used your torrents before for downloading The Sims 3 and have had a very good experience, so I decided to download your Sims 4 torrent. The download was very quick, but I encountered a problem with the installation.
Everything installs smoothly until this message pops up

I am running the installer as an administrator and have tried making the installation location (C:\Program Files (x86)\Electronic Arts\The Sims 4) Not read only. I have also tried changing the security permissions to allow full control, but this still doesn’t grant the installer access for writing the files. If I click ignore I get this message:

Clicking on retry causes the same message to appear and forces me to cancel the installation. 
This is probably just me being dumb and i'm sure it can be easily fixed

Also obviously I can't apply the Ultimate Fix because the game doesn't get installed

Thanks for replying, I used 7Zip to extract everything but i'll try WinRar now and see what happens

So I extracted the .rar file with WinRar, but I still seem to get the problem

That seemed to have fixed the problem. It installs fine now. 

Thanks!

Helper edit: Problem solved, topic closed. Have fun!
