Getting the NSIS error when installing Ubisoft Connect on Windows? It’s usually due to a corrupted installer or antivirus interference. Follow these easy steps to resolve the issue quickly:

✅ Step 1: Completely Close Ubisoft Connect

  • Press Ctrl + Shift + Esc to open Task Manager.
  • Find UbisoftConnect.exe, right-click it, and select End Task.

✅ Step 2: Temporarily Disable Antivirus or Firewall

  • Turn off Windows Defender Real-time protection or your antivirus briefly.
  • Antivirus programs often mistakenly block Ubisoft’s installer.
  • Download and run the January 2025 Ubisoft Connect installer (trusted by the community).
  • After installation, Ubisoft Connect will automatically update itself.

✅ Step 4: Run Installer as Administrator (Compatibility Mode)

  • Right-click the Ubisoft installer → Properties → Compatibility tab.
  • Check “Run this program as administrator”.
  • If problems persist, select compatibility for Windows 8 or Windows 10.

✅ Step 5: Install from Microsoft Store (Alternate Method)

  • Open the Microsoft Store, search “Ubisoft Connect”, and install directly from there.

Following these steps will resolve the Ubisoft Connect NSIS error quickly and reliably. If you still encounter issues or need further assistance, reaching out to Ubisoft Support or exploring community forums like Reddit can provide extra help. Happy gaming!
