If Windows blocks the installer

The first time you run AnnonAppInstaller.exe, Windows may show Windows protected your PC. Microsoft Defender SmartScreen does that for apps it does not recognize yet. Ours is not a widely known publisher, so Windows asks you to confirm. Leave SmartScreen on. Do not turn off Windows protection. Click More info, then Run anyway.

What you are installing

The installer adds the Annon App add-in for supported Revit years on this machine. It does not replace Revit, and it does not require Dynamo. Your free key is valid for one year on up to two machines. License details also live on the About button on the ribbon after install.
