Additional Notes:

IIS 4.x and up can use a .cer file.
This file contains: Root, Intermediates, and domain certificate; all rolled into one file (PKCS#7).
IIS 6.x and up will accept a .crt (end-entity/domain certificate) file, but Root and Intermediate(s) will need to be installed manually.
Apache makes use of a SSLCertificateChainFile in which we give it a file extension of .ca-bundle file.
This file contains the Intermediate(s) and sometimes Root certificates in a single file.
Some Comodo Partners have their own Comodo certificate hierarchies. If you are unsure of your certificate hierarchy, please contact support by submitting a support ticket
For Comodo InstantSSL you can download Comodo Intermediate and Root Certificate from here.
