Your graphics card does not meet minimum requirements, that might be the reason (yours has 68 MB dedicated memory, the sims needs 128). The game has more or less been able to run on even lower specs than minimum reqs, but Cats&Dogs need the right specs.
Your windows is not updated, try updating it and then updating your graphics card, it might help!
You can also try resetting your files to factory settings. (do the things above first!)
- Make a backup; copy your The Sims 4-folder from C:\Users\Username\Documents\Electronic Arts to an external drive or somewhere else on your computer, for example your desktop.
- Rename the The Sims 4-folder in C:\Users\Username\Documents\Electronic Arts to The Sims 4_backup
- Start the game, make a new save, and see if the error is gone.
(The game will have created a new The Sims 4-folder in your documents, this is supposed to happen)
- If yes, continue
- If no, post a reply telling us the error is still there
- Start putting folders back in the new The Sims 4-folder. Observe! After every file/folder, start the game and make sure it still works, before putting in the next one.
- Options.ini - your game settings
- Saves - your old saves. The sub-folders are not needed. If putting these back causes problem, try putting one back at a time.
- Screenshots
- Custom music - if you have any
- Tray - your library objects; like lots, rooms and sims
- Mods - your mods and cc, might cause problems when putting back
If putting back one of the folders was problematic and you did not work it out, please post a reply and we'll see if we can find what your problem is!
