Only the first installer (not the installers the first installer runs) will run as an admin.
Part of the issue is that if you run an installer that runs other installers, it doesn't work on Windows 10 if all the installers have to be run as admin to work. Still, I would LOVE to see them re-release Sims Complete Collection on Origin, updated for Windows 10 and later systems, since so many have trouble with the installation. I have all my old disks AND Sims complete collection.
