About installing root and intermediate certificates

You might need to install additional certificates for the following situations:

• When the main certificate you installed contains an intermediate certificate, a root certificate, or both in its certification path.
• When the PFX file you imported contains an intermediate certificate, a root certificate, or both embedded within it. In this case, the certificates might not have been installed in the correct locations.
