My task is to install a certificate which I got in .p7b format from my company. IIS 7 can import a certificate in .cer format by using the "Complete Certificate Request..." option. Using the Certificates MMC snap-in I managed to convert the .p7b file to .cer by importing, then exporting it.
Unfortunately when I try to use it with the "Complete certificate request..." option, IIS 7 complains that it can't find the certificate request, so it can't proceed.
What options do I have in this situation? Do I need a .pfx file which has the private key in it, or I can install the certificate in .cer format? I want to use it in an https binding with one of the websites on the server.
