Hello TatarG,
Those dll files that you mention seem to part of the Microsoft C runtime.
What I would suggest that you try is completely uninstall both Hearthstone, and the Battle.net app, from your system.
After this, download the app from this here, and make sure that you install it as an administrator.
I hope that this will help out!
