Hi,
looks like I cant properly update my game to 15.10 from 15.9.

Error Message says : "Error opening update package: File C:/Program Files/Factorio/data/../doc-html/Classes.html not found"

Any idea how to fix that? Thank you.

For some reason the Classes.html has a different content than the updater expects (Known issue viewtopic.php?f=41&t=29291&p=272029#p272029).

Your only option to resolve this is to download the installer/zip from the website and apply that.

Fixed it. Thank you.
