Downloading/Updating Management Portal for Windows
When you are downloading or updating your Management Portal in your Windows PC, you may see this warning dialogue from Windows Defender SmartScreen. This is because of a stub update in Projector- Microsoft has changed their security algorithms in the last couple of years, and there is not much we can do to avoid this message. Eventually though, when enough users proceed with the update, Microsoft will “trust” the updated Management Portal, and the dialogue will not appear for remaining users.
To continue with the update, click the "More Info" and then "Run Anyway" options.
