You have downloaded the last version of the Rainbow Desktop App. When you start the setup, Windows Defender blocks the install to protect your computer with the message "Windows protected your PC".
Rainbow Desktop App uses a Digital Certificate to be considered as safe by Windows 10. This certificate has a limited duration and must be regularly renewed. In case we use a new certificate, it could take few days to be validate by Microsoft ®.
Pending this approbation, Windows Defender can consider Rainbow Desktop App installer as unsafe and block the setup.

- Click on the link "More info" below the Windows Defender message.
