Problems finding folder to apply the Fix

Hey guys - I'm having a similarish problem. 

I have Sims 3 Base game on Origin, along with Generations (both of which I installed from disk) 

I just downloaded Show Time from you guys and it installed without a problem, when I ran the game and got to the Neighbourhood section, I got an error message saying that my Graphics Card isn't installed. 
It wouldn't give me any options to choose a neighbourhood, create a new game, the drop down list was blank and it wouldn't allow me do anything. 
So, I closed and re-ran. This time, it says that I need to insert Disk for Showtime. 

I have the latest version on my launcher. I downloaded and applied the Ultimate fix but I'm still a little confused. Did I do something wrong? Since Showtime didn't go into Origin and in C / programme files / electronic arts /  is only showing Showtime and Generations, and not base game, should I be applying the fix to somewhere else? I think this could be where I'm going wrong. 

My apologies if this question has been answered somewhere else - I'm new 

Thanks in Advance!

Hey, 

I just noticed this. Lol. 

Thanks - I'm gonna try all the steps again and see if that works. I'll keep you updated!
