Q: App Store error: This version of OS X 10.11 cannot be installed on this computer.

I am trying to upgrade my OS to El Capitan from Lion. When I try to get it from the App Store, I get the error message:

"This version of OS X 10.11 cannot be installed on this computer."

 

I have a mid-2011 27" iMac which should be compatible, according to the Apple website specs. Any ideas what the problem might be?

 

Thanks!
