ERROR: App can't run on your PC. Tried all options found on internet to fix

I downloaded a version of the Sims to my Windows 10 PC just an offline play zip file. Keep getting the error message App can't run on PC. I have tried every solution I can find as to why this keep popping up. I'm at a loss. Maybe I am missing something small & I'm just an idiot but any suggestions would really help :)

The App is made for another platform. Please verify the specification/information on the page from where you downloaded the file (or post the link here for a more specific answer).

Just in addition:

• A zip file can contain anything, it doesn't say anything about the platform the App is for.
• It doesn't look like a permission issue at all.

Update

Look here: https://steamunlocked.net/the-sims-4-free-download/ and the "HOW TO RUN GAME!!.txt", as described in the first comment.
