From March 2026, some users may experience a JavaScript error when launching Nero Start, or Windows Security and Smart App Control are blocking temporary .node files that the application needs to run. This is because recent Windows 11 security updates now flag certain file behaviors more strictly, preventing Nero Start from starting properly.
We have released an updated version that resolves this compatibility issue. Please download and install the latest Nero Core from https://www.nero.com/download.php?id=nerocore_full_installer . Then run Nero Start 28.5.61.0 or higher version to restore full functionality.
