I get the following error when trying to install update:

Update failed: Checking update packages failed: File C/Program
Files/Factorio/data/_/doc-htmltypes/FluidIngredientPrototype.html has unexpected
content

Our updater needs the original unchanged file to apply the update. In case of changes, filesystem errors you need to download a fresh copy of Factorio https://factorio.com/download
