My Downloaded Sims game keeps saying it isn’t downloaded

avocado_naii  Where is Sims 4 installed, when it's installed, according to the EA App?  You can see the location under Sims 4 > Manage > View properties.

If it never shows as installed, even after you download it, you should be able to see the download location when you try to install it again.

Please also let me know what antivirus you use.

Thanks for getting back to me! 

I don't use an antivirus and I fixed that issue but I have another issue because my game keeps reading an error code, it says "core/sims4/tuning/tunable .py". it's crashing my game, loading my game slow and when I try to click on things in my game it's slow as well. I thought it might of been from Lot 51 core but I deleted it and i'm still having this issue. I would appreciate the help because I don't know at this point. 

avocado_naii  Does this happen with no mods or custom content at all?  Please test if you haven't already.  You don't need to save your progress.

If it does happen, please post a screenshot of the error.  Please also look for a new lastexception file in Documents > Electronic Arts > The Sims 4.  It would be best to delete your current ones first, then see whether the game creates a new one.  If it does, open the file, delete the first line of text, and you should be able to attach it to a reply here.

This the report when I first open the game. 

This the report when it takes me to the web page 

avocado_naii​  I don't really know what to do for this kind of issue, so I've moved your post to the Mods forum for better help.
