"Files in your Heroes of the Storm installation are damaged"

I have installed the game and when I try to launch it I get the message that “Files in your Heroes of the Storm installation are damaged”. I have uninstalled and reinstalled the game, as well as run the in-app “scan and repair” function which is saying that there is nothing to repair. I still cannot play the game.

This issue can usually be resolved by following the steps here.

Should the issue continue after you try the above then you can also try removing the Heroes of the Storm folder located here - %userprofile%\Documents\Heroes of the Storm
