Installing SSL Certificate for use in IIS7, installation "works", but cert listing disappears

The certificate was not exportable, so I was unable to use Roberts suggestion. Ultimately, I had to rekey the certificate at the Go Daddy account management page, and install it on both servers again. Some of the options during the wizard for the install on IIS6 were grayed out for me, and my initial attempt on that server failed. I ended up installing the certificate on the new server (IIS7), and then exporting that certificate in a .pfx format, and then importing that version into the IIS6 installation. At which point everything started working.
