So you should uninstall it all, clear the Registry, re-start computer, re-install the games, carefully following the step-by-step guide from here

How to clear the Registry

Go to the computer the game is installed upon. If the computer is
using Windows XP, 98, or any older version of Windows, click Start >
Run; in the box, type regedit and hit the enter key. For Windows Vista or 7, type regedit into the "Search programs and files" box, then click regedit.exe.
In the window that opens, click the + sign next to the words
"HKEY_LOCAL_MACHINE". You should now see several more folders, such as
"SYSTEM" and "SOFTWARE". Keep opening folders, in this sequence:

• HKEY_LOCAL_MACHINE
  
  
  
  • SOFTWARE
    
    
    
    • Wow6432Node (This folder will only appear if you have 64-bit Windows! If not, ignore this step.)
      
    • EA Games
      
      
      
      • The Sims 2
        
        
        
        • ergc
          
      
      
    
    
  
  

If you need the key for one of your expansion packs, look under the
appropriate folder in EA Games, such as The Sims 2 Open for Business.

In the pane on the right, you will see a line named default,
reg_sz. In the column entitled Data you will see a string of letters and
numbers. This is the license key for your copy of The Sims 2.

• Write it down in a safe place - some people write it on the
  Sims 2 disc with a special CD/acetate pen (NOT a ballpoint pen!), or on a
  bit of paper inside the CD case, or even into a text file that you can
  save somewhere you'll remember.
  

• When you have finished, close regedit.
  

Delete the files to clear the Registry.

I read all the posts that have been recommend and have downloaded the ultimate fix file. When I first copy over the files to the base game the error disappears, it's not until I load Generations or Pets on (the ones where I need to copy of the files to the base game instead of expansion packs) that the error comes back up. I have followed each step carefully to that of the guide given, not missed any or changed anything.

I have tried uninstalling everything and cleared the registry but still the error comes up. I tried starting from the start up in the bin file but then a different error comes up. 'Unable to start game - Service Initialization Failed.'

Can anyone help? I would really appreciate it x
