Assassin’s Creed (AC) Valhalla won’t Launch – Game Failed to Start – How to fix

AC Valhalla just won’t launch. Why is that?

Assassin’s Creed Valhalla is, without a doubt, one of the most anticipated gaming titles of the year 2020 and you can easily tell by looking at the reception it is getting from the community and the reviewers.

But not everything is perfect for the game at this very moment. Why is that? A lot of posts have started popping on the forums. And what are these posts about? Well, it looks like a lot of players are having problems at getting the game to launch. The effort to start the game on PC is getting failed for a lot of users. Now for some, it could be because of the low powered hardware in their systems. But even people who are sitting with RTX 2080s and i9-9900Ks are also facing this issue. So one thing is confirmed, this problem has nothing to do with PC hardware. Maybe for some, but definitely not for everyone.

Now the main question is, are there any fixes for this issue? You see the problem is, it is hard say specifically what is causing this issue. Startup issues can be triggered by various things. And the situation is different for different users. And if the issue is from the side of developers, then forget fixing it by yourself. Still, here are some fixes that you can try.

How to fix this issue?

The first thing you should consider doing is, try running the executable file or .exe file of AC Valhalla as administrator. Just head over to the folder where you have installed Assassin’s Creed Valhalla. Right click on acvalhalla.exe and select Properties. Now click on the Compatibility and check the box beside “Run this program as an administrator”. Start the game directly by double-clicking on the exe file, instead of launching it via Ubisoft Connect or Epic Games Launcher.

Check whether your Anti-virus software is blocking AC Valhalla/Ubisoft Connect/Epic Games Launcher or not. This has happened to a lot of games this year, it was the same case with Watch Dogs Legion when it launched. The executable of Assassin’s Creed Valhalla or the launchers associated with it may be getting silently quarantined by some antivirus software, preventing the game from launching. Therefore, you may need to disable Real-Time Scanning function or Real-Time Protection function of your Anti-virus to play. If you do not want to completely disable the software, then you will have to add the .exe of AC Valhalla and Ubisoft Connect/EGL on the Exceptions list of your AV Software.

Don’t have a third-party Anti-virus software on your system, and using Windows Defender instead? Here is how to add Assassin’s Creed Valhalla on the exceptions list of Windows Defender:

  • Go to Windows 10 settings
  • Click on Update & Security
  • Select Windows Security from the left sidebar
  • Click on Virus & threat protection
  • Under Virus & threat protection click on Manage settings
  • Under Exclusions click on Add or remove exclusions
  • Click on Add an exclusion
  • Select File
  • Select the .exe or executable file of Assassin’s Creed : Valhalla
  • Restart your PC

Also try downloading and installing the latest version of Visual C++ redistributable, as there’s a chance it hasn’t been installed correctly.

And finally, if none of the fixes mentioned above work for you then there is no other choice but to re-install the game completely. We are still testing the game. More fixes on the way!
