Automatically prompted to open EASetup.exe when copying over the Seasons expansion

As said in the title, my pc automatically tries to run EASetup.exe when I try to unzip and copy the Seasons files over to the main game. If I click no on the user account control popup it seems to cancel the copy operation completely. Do I hit yes or is my unzipping program just broken?

It tries to run it because you dragged the files on that exe file. Just to make sure it works fine: extract them to subfolder, open it, select all, copy, open your "The Sims 4" folder and paste.
