Depending on your choice of browser, the following options for installing your certificate are available:

PKCS#12 file download (P12)

This doesn’t require any software installation. It will download your new certificate to a file that you must then open to complete installation.

Legacy Internet Explorer (IE)

This uses an ActiveX component to install your certificate to the Windows certificate store.

This method is used automatically whenever you use Internet Explorer (or Edge in IE Mode) to complete installation. You won’t be given a choice of other methods.

Certificate Signing Request (CSR)

This is only suitable for advanced users who use software or a hardware device to generate a CSR. The CSR (PEM format) is manually submitted to DigiCert during the installation process and a downloadable certificate (PEM and DER formats) is produced.
