@tokyo_xo and @dahliap If you have the CAS Demo installed, please see this thread:

Otherwise, please run a search for EP13 , which is the folder for Growing Together. Open a File Explorer window, click This PC in the left panel, and enter EP13 in the search field in the upper-right corner. Wait for the search to finish, then make sure the full file path is showing under each result. If it's not, expand the window sideways as necessary. Take a screenshot using Windows key-shift-S and attach it to a reply here.
@dahliap Are you saying you installed Sims 4 into Documents > EA Games? This isn't ideal, and if it's not too much of a burden, I'd suggest uninstalling the game and reinstalling it to either its default location, which is Program Files > EA Games, or to another folder not within Documents. If, however, you installed the game into Documents > Electronic Arts , then this is a major problem because this is also where the user files are stored, and having both sets of files in the same place can and will cause all sorts of problems.
@Gagea25 The Delta folder holds patch data only, not the original data for the pack. So moving the folder in Delta into the main Sims 4 folder will not only fail to make the pack load, it could prevent the EA App from properly installing the pack if the player tries again. Growing Together doesn't have a folder within Delta yet because it hasn't gone through a patch cycle yet, but that will happen soon enough.
