1.The purpose of the article
This article will guide you on how to fix the error that Sophos Endpoint could not be installed even though the installation file was executed on Windows 10.
The cause of the failure to install Sophos Endpoint despite executing the installation file is because the Windows 10 computer lacks a certificate named DigiCert Trusted Root G4.
This is one of the certificates required to be able to install Sophos Endpoint. If the computer does not have this certificate, when executing the installation file, the installation window of Sophos Endpoint will not appear.
3.How to fix.
To fix the error we need to download DigiCert Trusted Root G4 and add this certificate to the computer or we need to update Windows updates.
In this article techbast will guide you to download and add this certificate to your device.
To download this certificate we go to https://www.digicert.com/kb/digicert-root-certificates.htm and choose the correct DigiCert Trusted Root G4 name and click Download DER/CRT to download.
Then we will add it to the computer.

Click File > Add/Remove Snap-In…
Click Certificate and click Add >.
Because we add the certificate to the computer, we need to select Computer account.
Note: if there is no Computer account option at this step, the reason is that we open mmc with non-admin rights.

At the Console1 window, we go to Console Root > Certificates > Trusted Root Certificate Authorities > right-click All Tasks > Import to add the certificate.
