sims 3 installation errors?

hello i recently downloaded the sims3 game and im having issues installing the base game. ive gotten to the end of the installation almost((?)) and it keeps telling me that specific paths cant be found and insert the correct disk (so i swap from start disk to disk1) this usually happens with sunset valley objectcache and something to do with build0/1?? how do i fix this so i can get the game to install fully. last time i downloaded the games wasnt through iso-ing?? and i had no problem with installing them )-: the installing bar has been loaded fully from what i can tell now for almost 4-5hrs with no progress still. any help would be greatly appreciated.



*after searching through the forums i only found one other person with the same problem im having right now. i closed all my torrent programs and anything else i wasnt using via task manager so i knew they werent running and im still having errors see below

yeah i use winrar, i extracted onto my desktop then mounted the iso's to disks as it says but i still get errors )-: ive even re-downloaded the torrent in case of errors and its still producing the same thing
