Ubisoft Connect is Ubisoft’s official game launcher and distribution platform, similar to Steam or Epic Games Launcher. It’s a critical application for gamers who want to play titles like Assassin’s Creed, Far Cry, Rainbow Six Siege, or The Division 2. It manages game installations, updates, cloud saves, achievements, and friends features across all Ubisoft titles.
However, many users have recently encountered a frustrating error during installation:
“Installer Integrity Check Has Failed”
This error prevents the Ubisoft Connect app from installing properly, leaving gamers stuck and unable to launch their favorite titles.
In this guide, we’ll explain what this error means, why it occurs, and exactly how to fix it using a method that works 100% of the time — by installing Ubisoft Connect via the Microsoft Store.
🔍 What Does “Installer Integrity Check Has Failed” Mean?
This error is essentially a security measure. It means the installer you’re trying to run is either:
- Corrupted during download,
- Incomplete,
- Or has been tampered with.
Software installers have what’s called an “integrity check” built in. It scans the installation file to ensure everything is intact and unmodified. If anything is missing or suspicious, the installer halts to avoid potential malware or crashes.
This can happen for several reasons:
- Poor or unstable internet connection during download
- The installer was downloaded from a non-official source
- Your antivirus interfered with the download
- System errors or temporary file corruption
✅ The Fastest and Easiest Fix: Install Ubisoft Connect from Microsoft Store
The simplest and most reliable fix is to bypass the standalone installer altogether and instead install Ubisoft Connect directly from the Microsoft Store.
Here’s how:
🔧 Step-by-Step Instructions
- Open Microsoft Store
- Click on the Start Menu
- Type “Microsoft Store”
- Open the Microsoft Store app from the results
- Search for Ubisoft Connect
- In the Microsoft Store search bar (top center), type:
“Ubisoft Connect PC” - Click on the official Ubisoft Connect app in the search results
- In the Microsoft Store search bar (top center), type:
- Install the Application
- Press the Install button
- Wait for the Microsoft Store to complete the installation (this process verifies and installs a clean version of the app)
- Once installed, launch the application from the Start Menu
- Verify That It Works
- If installed correctly, you should now be able to open Ubisoft Connect without seeing the integrity error
- Log in to your Ubisoft account and begin using the app normally
💡 Why This Method Works
The Microsoft Store version is:
- Officially maintained by Ubisoft
- Automatically updated and integrity-checked by Windows
- Immune to third-party installer issues
- Free from corrupted or partial download problems
This makes it the most stable source for installation compared to downloading the setup file from other sites or even Ubisoft’s direct website (which sometimes fails due to CDN caching or antivirus blocks).
🧽 Bonus Tips If You Still Encounter Issues
If, for some reason, you still face errors after trying the Microsoft Store version, consider the following:
1. Clear Old Installer Files
Go to:
C:\Program Files (x86)\Ubisoft\
Delete any leftover folders from previous installations.
2. Disable Antivirus Temporarily
Sometimes your antivirus software may block or interfere with Ubisoft’s installer. Temporarily disable it and try again.
3. Use a VPN
If you suspect a regional download issue or ISP caching problem, try using a VPN to change your download location and reattempt the install.
🎮 Final Thoughts
Errors like “Installer integrity check has failed” are annoying, but the fix is simple and doesn’t require any technical skills. By using the Microsoft Store to install Ubisoft Connect, you’re guaranteed a clean, verified version of the launcher with minimal fuss.
💬 Pro Tip: Always download software from official sources like the Microsoft Store, App Store, or the developer’s website to avoid integrity and security issues in the future.
Now you can get back to exploring the world of Assassin’s Creed, battling it out in Rainbow Six Siege, or going on co-op missions in Ghost Recon — with no installation headaches!
