Can't update from 10.10.5 to 10.11

My poor old machine (MacBookAir) is still running Yosimite 10.10.5. I worked and worked to get enough memory free so it could at least update to El Capitan. I downloaded the installer and it said it went through the whole process successfully to install El Capital. I restarted the machine. When I go to "About This Mac" it still says it's running Yosimite 10.10.5. WHY. Where did the update go? Why won't it run? I've been trying to fix this for a couple years now and it got me at my wits end.

MacBook Air 13″, OS X 10.10

I did that. It fully installed. But it's still saying it's running 10.10.5. My machine is a MacBook Air, 13inch, mid 2012. All the specifications should be correct for ElCapitan. I don't know why it's not running.

The download placed an installer in the Applications folder. Run that to upgrade the OS.
