Can't find the Sims game on my pc

@kasjumsir  Try downloading the game to the location where you can see it already.  By that I don't mean the folder in Documents > Electronic Arts, and in fact please don't try to download it there.  Find the location where the game's program files are, for example probably one of these:

C:\Program Files\EA Games\The Sims 4

C:\Program Files (x86)\Origin Games\The Sims 4

If you can't download the game again, please uninstall it with Revo Uninstalller.  Here's how:

• Put aside your Sims 4 folder in Documents\Electronic Arts and rename it to something that doesn't include the words "Sims 4."
• Download Revo Uninstaller (the free version is fine) from here.
• Launch Revo, select Sims 4 from the list, and click Uninstall.
• Once the game is uninstalled, select "Moderate" under "scanning modes," and click Scan.
• Review the list, in case there's something you want to save; otherwise, click Select All, and then Delete.
• Close Revo, and restart your computer.

Uninstall the EA App with Revo as well.  I don't have instructions for that at the moment, but the process should be straightforward.  Restart again when you're done.

Install the EA App, then Sims 4.  Again, don't install it into Documents or any subfolder there, but pretty much any other location is fine.
