Ubisoft - Uplay App/Game IDs on Windows

Get Ubisoft - Uplay App/Game IDs from the Windows Registry for any installed games with the uplay://launch/{ID}/0 (URL Scheme Handler)

Why would I ever need to use this?

If you own any games from Ubisoft prior to the introduction of their "Ubisoft+ Games Subscription". Such as Assassin's Creed® IV Black Flag™ Gold Edition, etc...

You could easily install your games along with its appropriate "Desktop Shortcut" that would allow you to launch the game.

However, if you ever Subscribed and/or Trialled out their Ubisoft+ Subscription service and later Cancelled it while having played the certain old games in the Ubisoft+ Catalogue you would have noticed a different App/Game ID being used to refer and launch the game.

---

Example:

If you downloaded Assassin's Creed® IV Black Flag™ Gold Edition from your owned games library while not in an Active Ubisoft+ Subscription. The following Desktop Shortcuts are created:

Assassin's Creed IV Black Flag (Singleplayer)

uplay://launch/565/0  

Assassin's Creed IV Black Flag (Multiplayer)

uplay://launch/565/1  

---

You will not be able to launch this game instead Ubisoft Connect will ask you to either Login and/or Activate a key

---

To FIX the ISSUE you would need to know the App/Game ID when you installed the game from the Ubisoft Connect Launcher.

Thus, running the UplayGameIDs.py will check the Windows Registry and retrieve ALL the Uplay App/Game IDs as well as display the URL Scheme Handler used to launch that specific game.

Changing the App/Game ID from 565 to 273 should fix any shortcut issues you have for this game and others....

Assassin's Creed IV Black Flag (Singleplayer)

uplay://launch/273/0  

Assassin's Creed IV Black Flag (Multiplayer)

uplay://launch/273/1

Alternatively, you might want to fix the Start Menu shortcuts which also are affected by the same issue.
Open Run using the "Windows Key + R" paste the below Path. Locate the Game shortcuts and modify the Properties to include the correct App/Game ID

%AppData%\Microsoft\Windows\Start Menu\Programs

NOTE: Uplay uses the following URL Scheme Handler
uplay://launch/{GAME_ID}}/{MODE}

MODE is a numerical value usual; 0 or 1; for Singleplayer and Multiplayer respectively. However, certain games like Tom Clancy's Rainbow Six Siege uses this to launch either the DX11 (0) or Vulkan (1)

uplay://launch/{GAME_ID}}/0 for Singleplayer 
uplay://launch/{GAME_ID}}/1 for Multiplayer
