Steam – Uplay Games not Launching

steamtechnical-issuesubisoft-connect

I have 2 Ubisoft games on Steam, Assassin's Creed III and Valiant Hearts. I've bought them a while ago, and they seemed to work, I've played them a lot.

But now, when I try to run them, the mouse icon loads for a few seconds and nothing. Nothing happens. I checked my computer processes and there is no "Valiant Hearts" or "Assassin's Creed III" process running.

I can't launch the game from the shortcut, nor steam, nor the Uplay launcher.

What I have tried:

  • Reinstalling Uplay: This seemed to work in the first place (before I did that, the uplay launcher wouldn't launch as well). After reinstalling, the uplay launcher started to launch, and I was able to play the games once, and then the problem returned. Now, I can open the uplay launcher, but can't launch any games.
  • Going Offline: I've read in some internet forums that going offline could help me. I tried. Nothing.
  • Update: Tried running all as administrator, didn't work.

I don't have anymore ideas. I don't think that this is an installation problem because I was able to play the games, the problem appeared out of nowhere.

Here are my device's specifications:

  • Windows 10
  • AMD FX Quad-Core Processor
  • NVIDIA GForce GT680
  • 8GB of RAM.

UPDATE

I don't know what happened. I didn't did anything, but today i just tried to start the games and they worked. It seems that uplay is pretty unstable. However, i'll leave the question (and bounty) open, if someone appears with a permanent solution (i don't know how long my games will be working).

Best Answer

I have similar problems with Uplay,

there are several posts of user around internet(reddit, Ubisoft forum and so on) complaining about those things.

There are two main and constant problems:

  • Can't download/update a Uplay Game
  • Can't open a Uplay Game

Every single forum, reddit post will tell you to:

  1. Open as administrator
  2. Reinstal the Game
  3. Reinstal Uplay
  4. Reinstal Dx
  5. Port foward
  6. Add Uplay+Game on trusted programs in Windows/Anti-Virus
  7. Close background application.

None of them will work.

If you get luck and receive support they will tell you to do the same again, but for no reason don't follow their advice to disable all windows services from msconfig because that may mess your computer and you will be unable to start windows again.

The only way to find what is really happening is investigating your computer.

You can check the Uplay logs here

Program Files (x86)\Ubisoft\Ubisoft Game Launcher\logs

(

And search google for the exact problem.

You can use the windows Resource Monitor to check the applications. And Windows Event Viewer for some anomaly.

Sadly, most of the time it was a problem with Ubisoft

Can't download/update a Uplay Game:

It was caused, most of the time, for a Ubisoft Server refusing to send a package, just one package (network log)

I found 4 possible solutions:

  • Wait
  • Change your IP, if your ISP allows that.
  • Try another ISP if you have two or more at home, you can use your mobile internet to download that last package.
  • Download it on a friend, or find a fried with the game downloaded/updated and copy to yours.

Can't open a Uplay Game

It could be caused by needing some third party software, but mostly by Uplay failing to verify it as yours or its dependencies (preventing you to play it), it may vary from game.

In this case I found only two solutions:

  • Wait (Uplay updates sometimes fix that, but not always)
  • Format PC (try in another computer first)

Don't forget to check Uplay logs before trying any drastic measure.
