How to Fix Uplay Installation Errors

By the end of this post, you’ll have the tools you need to resolve any installation error and get Uplay or Ubisoft Connect up and running on your PC.


Common Uplay Installation Errors: Understanding the Issues

Before we dive into the solutions, it’s important to understand the errors you may encounter while installing Uplay (or Ubisoft Connect). The most frequent installation errors include:

1. NSIS Error: Ubisoft Connect Installer Integrity Check Failed

The NSIS (Nullsoft Scriptable Install System) error occurs when the installer for Uplay fails the integrity check. This prevents the Ubisoft Connect (Uplay) application from installing on your system. The error typically appears during the installation process and stops you from proceeding further.

If you receive an NSIS error or an installer integrity check failed message, it indicates an issue with the installer file. This problem often occurs due to corrupted installer files, insufficient system permissions, or conflicts with antivirus software or a firewall blocking Uplay.

2. Ubisoft Connect “Unable to Start Download” Error

This issue arises when Uplay fails to start downloading a game. The unable to start download error may occur due to game download issues, internet connection problems, or DNS settings blocking the download process. You may also face this error if Ubisoft Connect fails to launch properly due to a corrupted installation.


Fixing the NSIS Error: Ubisoft Connect Installer Integrity Check Failed

One of the most common installation errors associated with Uplay is the NSIS Error. This occurs when the integrity of the installer file is compromised. Below are the steps you can take to fix this issue.

1. Skip Integrity Check Using the /ncrc Command

One of the quickest ways to resolve the NSIS error is to bypass the integrity check by using the /ncrc command. This command allows you to skip the integrity verification during installation, allowing the process to complete.

Steps to Use the /ncrc Command:

  1. Open the Command Prompt by pressing Windows + R, typing cmd, and pressing Enter.
  2. Drag the downloaded Ubisoft Connect installer into the Command Prompt window.
  3. After the installer path, add the /ncrc flag (e.g., C:\Users\YourName\Downloads\UbisoftConnectInstaller.exe /ncrc).
  4. Press Enter to run the installer.

By using the /ncrc command, you skip the integrity check, which may resolve the issue if the installer file is safe and not corrupt.

2. Download Ubisoft Connect from the Microsoft Store

If the error persists despite using the /ncrc command, try installing Ubisoft Connect from the Microsoft Store. Many users have reported that downloading the launcher directly from the Microsoft Store bypasses the installer integrity check errors and installs the app without issues.

Steps to Download from the Microsoft Store:

  1. Open the Microsoft Store from the Start Menu.
  2. Search for Ubisoft Connect.
  3. Click Install to download and install Ubisoft Connect.

Using the Microsoft Store is an effective way to ensure you are downloading a verified and up-to-date version of Ubisoft Connect.

3. Download an Older Version of Ubisoft Connect

Another potential fix for the Installer Integrity Check Failed error is to download an older version of Ubisoft Connect. Sometimes, the latest version may have compatibility issues or bugs that prevent successful installation.

Steps to Download an Older Version:

  1. Go to a trusted website like Uptodown to find older versions of Ubisoft Connect.
  2. Download a previous version of the installer.
  3. Run the installer as you normally would and follow the on-screen instructions.

Older versions of Ubisoft Connect may have fewer issues and can bypass the errors encountered in the latest build.


Fixing Uplay Download Issues: Uplay Is Unable to Start Your Download

If you are unable to download or update a game through Uplay, you are likely encountering one of several common issues. These include DNS problems, permission issues, antivirus interference, and installation folder problems. Let’s go through each fix step-by-step.

1. Use Google’s DNS Address to Resolve Network Issues

One common cause of Uplay download errors is DNS issues. Changing your DNS settings to Google’s free DNS can help resolve network-related problems that prevent downloads from starting.

Steps to Change DNS:

  1. Open Control Panel and go to Network and Sharing Center.
  2. Click on Change adapter settings.
  3. Right-click your network connection and select Properties.
  4. Under Internet Protocol Version 4 (TCP/IPv4), select Use the following DNS server addresses.
  5. Enter 8.8.8.8 as the Preferred DNS server and 8.8.4.4 as the Alternate DNS server.
  6. Click OK and restart your system.

After changing your DNS settings, try launching Uplay again to see if the download starts.

2. Flush DNS Cache and Reset TCP/IP

If DNS issues persist, you may need to flush your DNS cache and reset TCP/IP to fix network configuration problems.

Steps to Flush DNS and Reset TCP/IP:

  1. Open Command Prompt as Administrator by pressing Windows + X and selecting Command Prompt (Admin).
  2. Type the following commands, pressing Enter after each one:
    • ipconfig /flushdns
    • netsh int ip reset
  3. Restart your computer and check if the download issue persists.

3. Run Uplay in Compatibility Mode

Running Uplay in compatibility mode can help resolve issues related to system settings and permissions, especially on older versions of Windows.

Steps to Run Uplay in Compatibility Mode:

  1. Right-click on the Uplay shortcut and select Properties.
  2. Go to the Compatibility tab and check Run this program in compatibility mode for.
  3. Select Windows 7 or another previous version of Windows.
  4. Click Apply and OK, then try to run Uplay again.

This ensures that Uplay runs in a mode compatible with older Windows versions, which may resolve any download issues.

4. Disable Antivirus Software and Windows Defender

Sometimes, antivirus software or Windows Defender can block Uplay’s functionality, including its ability to download or update games. In these cases, temporarily disabling these programs may resolve the issue.

Steps to Disable Antivirus and Windows Defender:

  1. Open your antivirus software and disable real-time protection.
  2. Go to Settings > Update & Security > Windows Security > Virus & Threat Protection and disable Real-time protection.
  3. If you’re using Windows Defender, you can also follow this detailed guide on how to permanently disable Windows Defender on Windows 10 and Windows 11.
  4. Restart your system and try downloading the game again.

Remember to re-enable your antivirus software once the download or installation process is complete.


Additional Uplay Installation Fixes

While the above solutions should resolve most issues, there are a few more steps you can take to ensure a smooth installation.

1. Verify Game Files in Uplay

If you’re encountering download errors with a specific game, it may be worth verifying the game files to ensure they are not corrupted.

Steps to Verify Game Files:

  1. Open Uplay and go to Games.
  2. Right-click on the game you are having trouble with and select Properties.
  3. Under Local Files, click Verify Files.
  4. Uplay will check the files and download any missing or corrupted files.

2. Rename the Game Folder

Renaming the folder of a problematic game can sometimes force Uplay to re-scan the files and resolve any issues related to game downloads.

Steps to Rename the Game Folder:

  1. Close Uplay and navigate to the game’s installation folder (typically C:\Program Files (x86)\Ubisoft\Ubisoft Game Launcher\games).
  2. Right-click the game folder and select Rename. Change the name temporarily.
  3. Open Uplay, and it will prompt you to start downloading the game again.
  4. Once the download starts, rename the folder back to its original name.

3. Reinstall Uplay

If none of the above solutions work, reinstalling Uplay can be an effective fix. Uninstalling and reinstalling the launcher ensures that you get a fresh copy and can often solve persistent issues.

Steps to Reinstall Uplay:

  1. Open Control Panel and select Uninstall a Program.
  2. Find Uplay and click Uninstall.
  3. Download the latest version of Ubisoft Connect from the official website or Microsoft Store.
  4. Install Ubisoft Connect and launch it to see if the issue is resolved.
