1914 Valour - FWWC Tournament Round 4

[Almskaar]

A reminder as the round ends tomorrow: updates for FWWC were released last week. Don't forget to update before starting the next round (but not during this round, for the games still in progress).

I'd like to upgrade my version using the patch rather than uninstalling the old and then installing the new. Can someone direct me to something that explains how to do that?
