Re: Combine sims 2 packs
@landihavinga , ok it will be a slow process and it's best to install one pack at a time so that they all sync up. Due to the age of Sims 2, unlike Sims 3 and 4 you will need to install the Expansion/Stuff packs in order of release. So, my advise is to install University start up the game and make sure it runs, then do the same with the next Expansion and so on.
Here is the link to the expansion pack installation order. https://answers.ea.com/t5/Other-The-Sims-Games/what-is-the-order-of-the-sims-2-expansion-packs/m-p/4797794#M11332
