For Honor in STEAM, not launching or starting.
無法在STEAM 開啟榮耀戰魂 。
First, make sure your computer has basic requirement.
I am sure you will, that isn't the main part.
首先，檢查遊戲的最低要求。如果沒有問題的話就看下一步。
Second, If you are running Ubisoft, that is the problem.
For Honor is a game of Ubisoft, even you install the game in STEAM. However, it will pass to Ubisoft. Before you run the game, Ubisoft is running.
The game is not launching/ starting or responing.
如果你本身也有運行著並登入 Ubisoft 的狀態下的話，這就是最重要的問題所在。
雖然STEAM 運行了榮耀戰魂，但它會跳到 Ubisoft 程式裡。
You can logout Ubisoft first, and run the game again.
When it pass to Ubisoft, It needs to login.
Once you login, link STEAM with Ubisoft.
先登出 Ubisoft，再到 STEAM 運行榮耀戰魂。當它跳到 Ubisoft 時， 會要求你登入並且許允 Ubisoft 連結到 STEAM。
Link Steam with Ubisoft
Require to enable "in-game overlay"
I didn't check the option.
You also can change the option in Ubisoft Connect app -> open settings (click on the tab with three vertical bars to access the settings page) -> under General, there should be an option that says "Enable in-game overlay for supported games".
It is done.
If the problem is not Ubisoft, you maybe update the Windows, download NVIDIA Driver, Visual C++ runtime and DirectX.
如果並不是因為Ubisoft 的問題，請先更新你的 Windows，並下載和安裝 NVIDIA Driver, Visual C++ runtime and DirectX.
Hope it can help you.
Enjoy it.
