When trying to install our desktop app on a Windows machine, you may see a prompt from Windows Defender that says "Microsoft Defender SmartScreen prevented an unrecognised app from starting. Running this app might put your PC at risk". Windows SmartScreen is part of Windows Defender which deals with unknown (uncertified) apps. If a third-party application is not certified, Windows will prevent it from installing or executing.
What to do when Windows Defender blocks unrecognised apps
Allowing the app to run and dismissing the prompt is a rather simple task:
- Click More info below the warning.
- Click on Run anyway
- You should be able to run the application.
