NavifiaSetup.exe
One installer sets up both the Excel and PowerPoint add-ins.
NavifiaSetup.exe
Installs both add-ins for your Windows user account. Microsoft 365 already includes the VSTO Runtime. On Office 2019 or 2021, install Microsoft’s VSTO Runtime first, then run this installer. If .NET Framework 4.8 is missing, Windows may ask for administrator approval.
Download EXESystem requirements
Windows 10 or 11 · Microsoft 365 or Office 2021 (Office 2019 also) · .NET Framework 4.8 and the VSTO Runtime · WebView2 for the Threads and Excel Links panes. After install, open Getting started.
Office 2019 or 2021? Install Microsoft’s VSTO Runtime before running NavifiaSetup. Microsoft 365 already includes it — you can skip this step.
Why does Windows show a warning?
The beta packages are unsigned. Read this before downloading, especially on a managed work computer.
Windows will show Unknown Publisher
The beta installer is unsigned, so Windows cannot show Navifia as a verified publisher. Download only from navifia.com, then use More info → Run anyway only if your organization permits it.
Managed devices may block installation
SmartScreen, AppLocker, WDAC, or company policy may block unsigned software completely. Do not bypass your employer's policy. Ask IT to review the installer and prerequisite list, or wait for an approved deployment.
