To install is for those with Macs that cannot run Sierra or still have If you Mac is compatible with Sierra, then you cannot install ElĬapitan unless you had previously downloaded it. Update2: Here is what someone says on upgrading from Yosemite to El Capitan in an Apple discussion thread: Where it is provided under the words 'get El Capitan from the App Store' Just reloading the page with Cmd+ R did not have the same success rate as clicking into the URL-bar and resubmit the request by hitting Return. So it seems a matter of retrying until success. Update: After that I tried the link a few more times by directly clicking or by copy paste it into the URL-bar. Anyway today the link lead me correctly to the El Capitan download in the App Store.

Maybe it was a server issue on Apples side or maybe it helped already having opened the App Store. I tried the link a few times but my App Store did not open. The following link, opened in Safari, should trigger the App Store to show the El Capitan download even if it is not already in the purchases list.
