App Store Installer for High Sierra (and Mojave) damaged?

I'm trying to upgrade my computer to High Sierra (minimally) or Mojave (not ready to go to Catalina yet), but the App store links I can find for both those OS versions gives me this message (same if I go to a link for Mojave). Ideas?

Look in your Applications folder and Downloads folder for "Install Mac OS...". Find and delete all previously downloaded installers, then restart and try again.
