Unable to download High Sierra

Everytime I try to download macOS High Sierra, the app store would always pop up with an error that says "This copy of the Install macOS High Sierra application is damaged, and can‘t be used to install macOS".


What can I do if this pops up? I'm just trying to upgrade my mac.

MacBook Pro 13″, macOS 10.12

Check in Applications folder for an Application called " Install High Sierra " if it exists. Drag and Drop to Trash and empty Trash.


Then follow directions from previous poster.

Corrupt File:

The file that keeps getting downloaded is corrupt. So, try downloading this by connecting through Ethernet, or by using another network, or by restarting your router. If of no success, then try this later on.
