How are houses installed?  You download the complete house   In the file you will find a mods folder and several other files. The things in the mods folder you have to put into your mods folder from the  Insert game. With most of them it is located under: Documents > Electronic Arts > The Sims 4 Unfortunately I can’t say how it looks like with the Mc users. The other files are the so called Tray Files, which you put into the Tray Folder of your game.( don't put tray files in subfolders )  You will find it just like the Mods folder :Documents > Electronic Arts > The Sims 4 Also activate the “moveobjects” cheat before placing the Lots. I have installed the house but cannot see it in the gallery, what should I do? In the gallery there is an option in the left sidebar: Custom Content. That must be activated. What is your name in the gallery? The same as everywhere - shinchanrk30 Which CC do I need for the house? With the exception of a few exceptions, all the CC’s that I used are always included in the zip file. And if not then the required CC are listed. Are the CC’s also included in the download? Yes, as already written above. Why is the apartment / house half empty or completely empty? Mostly after the game updates there are problems with the CC’s. Therefore, it may not be compatible with the Game version are. Unfortunately I have not found a solution on the net. Do I have to update my game to use the properties? Yes, in most cases. My game updates itself, so it is always guaranteed that it is up to date. Why are some CC highlighted in red and cannot be placed? This means that you only have recolors of the mesh in the game but the mesh is missing. Since I use a lot of CC I can’t look after every mesh. In the game you can see where the mesh is from and search for it with google. My Sims cannot enter the house, I receive an error message. What to do? Well, I can’t answer that because all pc / laptops are different. I am not technically proficient that I can simply analyze it. Please use the search function in your browser or go to the EA Games website and ask about this error message. Error code: 132:46bd3af9c82fc3b6 appears The CC’s of Dearnon are not compatible after the last updates and cause this error code But other CC’s can also be broken. In my case it is only the CC’s of Dearnon. Why don’t my Sims use the front door but always go through the back entrance? Unfortunately, I found that not all CC doors work anymore . In this case, just replace it.
