Missing of root certificate on some system versionsWindows

On some versions of Windows®, especially earlier versions such as Windows XP/2003®, Windows Vista®, and Windows 7®, there may be no official Comodo root certificate needed for our products to work properly.

Typically, this certificate is downloaded with Windows updates. But in case of its absence, the system does not recognize our software as trusted and shows unnecessary warnings that interfere with users’ work. And you need to download it from the official Comodo website and install it manually.
