I have Sims 3 instaled on my PC and wanted to install the expansion game. The problem is that the expansion come with another regional code that doesn't coincide with the main game.
The expansion set is for Europe and the main game is for the US.
I need help and change the regional code.
Solution
Go to Start > Run > type "regedit" to open the registry editor.
Go to HKEY_LOCAL_MACHINE/SOFTWARE/SIMS/IMS 3.
On the right you will see a file called SKU,
Double click to edit and replace the hex value displayed by 2.
