How to Fix Uplay Fails to Launch

Why Uplay Launcher Is Not Working?

The most common reasons that Uplay fails to launch on Windows include:

  • Third-party services conflict
  • Missing .DLL files
  • Conflict with Antivirus software
  • Corrupt cache
  • Incorrect Compatibility settings
  • Outdated Graphics drivers
  • Corrupted Uplay installation files

Method 1: Run Universal C Runtime

When you install Uplay, it automatically installs all of the prerequisites on your computer. However, there are times when some of these are overlooked because either they already exist on your device or a failure occurs during installation. Universal C Runtime is one of the most important external files for Uplay. You can install it as described below:

1. Download the Universal C Runtime for the Windows OS version on your computer from the official website of Microsoft.

2. Run the Universal C Runtime installer with administrator privileges. Right-click on the .exe file and select Run as administrator.

Ensure that the Universal C Runtime installer is run with the Run as administrator option selected.

3. Finally, restart your PC to save changes and launch Uplay.

Method 2: Clear Uplay Local Cache

As previously stated, Uplay stores all temporary configurations in a local cache on your machine. These configurations are retrieved from there and loaded into the app whenever Uplay is launched. However, on countless occasions, the cache gets corrupted, and Uplay fails to launch. In this method, you will learn to clear the Uplay cache:

1. To open the File Explorer, press Windows key + E.

2. Go to the following address: C:\Program Files (x86)\Ubisoft\Ubisoft Game Launcher\cache

3. Delete the cache folder’s entire contents.

Restart the computer again and run Uplay.
