The Fix #Crack replacement issue. [SOLVED]

I have installed tried to install The Sims 3 Seasons by using the Fix you have suggested to others with the same problem. I have downloaded all the other Sims 3 Expansions and they work fine. However, my Sims is the 1.42 version already and when I try to insert and replace the old .dll code in any of the game folders, it says 'You need permission to perform this action'. I do not have any problems when I replace the .exe file however. Any suggestions on what the problem might be and how I could fix it?

I didn't before. I did and it worked. Thanks very much for your assistance!
