Back up your data, check your applications for compatibility, click here, and then on the download link for El Capitan or Sierra. Once you've upgraded to it, you can use the High Sierra one.

It keeps telling me that the installation was successfully but nothing happened
and I can’t download macOS High Sierra it requires macOS version 10.8 or later
Chose Applications from the Finder's Go menu and run the installer.
