Re: can't install sims 4
@Sm0lPl4nt Please clera the EA App's cache and restart your computer.

Before trying to reinstall Sims 4, run a search for any related files. Open a File Explorer window, click This PC in the left panel, and enter Sims 4 in the search field in the upper-right corner. Let the scan finish, which could take a while, and review the list for any Sims 4 data. The folder in Documents > Electronic Arts can stay, but if you find anything else, please post a screenshot of the search results.
If you only find the Sims 4 folder in Documents > Electronic Arts, you can try installing the game again. If it still gets stuck, clear the App's cache again and restart your computer, then create a new folder on the root level of the drive of your choice. For example, C:\Games is fine, but not C:\Program Files\Games. Direct the EA App to install Sims 4 into this folder, not the default location.
