If Windows warns you
Each release is freshly published, so SmartScreen may show a notice until reputation builds for the new version. It is a reputation prompt, not a virus detection.
NexusAI installs no services, drivers or background auto-updater, and changes nothing outside its own folders. If antivirus flags the file it is a false positive. There is no need to disable your protection: contact support and we will help.

What's in Version 1.3.4
Free trial and a new home in Revit
Individual plans start with a 14-day free trial. The NexusAI button now sits on the Add-Ins tab with the new icon, and F1 over it opens the help page.
Stays connected
The add-in reconnects by itself after an outage, tells you when your computer was signed out instead of spinning, and lets a second account take over this computer after you confirm.
Longer runs, steadier models
Large jobs can run for up to 10 minutes. Save As no longer interrupts a task, closing your last model clears it from the dashboard, and a failed placement can no longer crash Revit mid-run.
