The Sims 2 is not installed properly

So i've downloaded The Sims 2, installed it, pasted a crack and when I try to run it, launcher opens. When i click "Play" suddenly an error, that says "The sims 2 is installed improperly please reinstall it" (or sth like that), pops up. I've noticed that the crack vanishes from the folder after the error pops up.  I thought it was the antivirus that deletes it, but I scanned a folder and crack and it doesn't see any malaware there.
P.S Sorry for my English

Welcome to the Forum @marysia and sorry for the belated reply,

Did you use WinRAR for extracting the contents of the download? Also, Windows Defender can delete things too. You should either configure exclusions or turn it off completely. Under Windows 10, read here on how to turn it off.

You can also re-download a new crack here:
