In this article, we’ll explore several effective methods to fix this error.
1. Install Using Microsoft Store
2. Try an Older Stable Version or Re-download from the Official Site
Sometimes, the latest installer may fail due to packaging errors, download corruption, or compression issues that trigger the NSIS error. In such cases, you have two reliable options:
Install a previously verified stable version known to work correctly. These versions are often more reliable and have been tested by the community.Re-download the latest installer directly from Ubisoft’s official website to ensure you’re using a clean, unmodified, and up-to-date package.
Once installed, Ubisoft Connect will automatically update itself if necessary. Note: While Uptodown is generally considered safe, it is still a third-party source. Only download from trusted sites and avoid unofficial mirrors. For maximum safety, consider verifying the file’s digital signature or hash if it’s available. If installing the older version doesn’t work, or if you prefer using the most recent files directly from Ubisoft’s servers, consider re-downloading the official installer. This ensures that you receive the latest, unmodified build with updated compatibility and patch fixes. It also helps if the error was caused by an incomplete or corrupted download.
3. Install Ubisoft Connect via Steam or Epic Games
Steam and Epic Games handle the installation and verification of Ubisoft Connect when it’s required by a supported Ubisoft title. This avoids issues like file corruption, incomplete downloads, or integrity check failures that may occur when downloading through browsers. This method ensures that you receive a clean, patched version of Ubisoft Connect bundled directly with the game, verified by the platform without manual steps.
