Normally, the GlobalSign Root Certificates are installed by default on Windows. However, they might not be present on older versions of Windows or when the System Administrator removed them previously.
If during the installation of the Endpoint Protector Client, the following errors related to digital signature are displayed: "A digitally signed driver is required" or "Microsoft Defender SmartScreen prevented an unrecognized app from starting", a GlobalSign Root Certificate has to be installed on the computer’s certificate store in the “Trusted Root Certification Authorities” section.
The official GlobalSign root certificates are available here:

Search for the certificate named: "GlobalSign Root R3" valid until 18 March 2029, download it and install it.
Additionally, for the digital signature time-stamping service, the following certificate from DigiCert needs to be trusted: "DigiCert Assured ID Root CA", valid until 10 November 2031. You can download it from this location:
