thekaffeehaus Try forcing the game to open in DirectX 11 mode. Open the EA App, click Sims 4 > Manage > View properties, and add -dx11 to the command line box.
liz1234567 As a test, please try playing in a clean user folder. Move the entire Sims 4 folder out of Documents > Electronic Arts and onto your desktop. When you launch the game, if it launches, a clean folder will spawn with no content. (Your saves and other content will be intact in the folder you've moved but temporarily unread by the game.) Don't add anything to the new folder yet; just start a new save and see how it runs, that is if you can get that far.
If you get another crash, please provide a dxdiag. Click Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop. From there, you can attach it to a reply using the paper clip (Attachment) icon included with the other formatting buttons.

de49iw4xmd8v There's a Portuguese Sims 4 tech forum here:
The Sims 4 Problemas técnicos & bug | EA Forums
If you'd like help in this forum, please post in English. In that case, I'd like to see a screenshot of the error you get, if any, when you try to install the game. It's fine if the error itself is in Portuguese.
