Need informations about installing extensions

Hi,
I'm about to install all the expansions with your instructions and in some installation guides it says "Update the launcher to the latest version" but when I launch the game it says "an error occurred" and in the launcher I see the 0.0.0.0 version.
I did the 1.67.2.0240xx update before installing the first expansion (I did not install Worlds Adventures, my first expansion was High End Loft Stuff), is that normal ? 
Do I continue installing all the other expansions and crack the game in final? Is the crack gonna change that ?
Thank you in advance

Hi there!

Have you read the installation guide thread properly? There's also an Ultimate fix that you need to download in order for the game to work properly. Also Sim Architect has made a video about proper installation of the Sims.

The order of which you install do not matter. You can install whichever EPs/SPs first. Let me know if you can't find Sim Architect's video.
