If you are using Windows Developer Preview and have difficulty obtaining or downloading a certificate using Internet Explorer 10 (IE 10), try using compatibility mode. Turning on Compatibility View is the same in IE10 as in IE9, so you can follow the instructions at "Why do some web pages look incorrect in Internet Explorer 9?" to make the chage. This tip was added to the Windows Developer Preview release notes as well.

I have seen an issue, where I was able to navigate to the certificate page using compatibility mode. However, when I click to submit my request, it informs me the site must be HTTPS. Is there an IE setting to remove this requirment for HTTPS?
If I understand your question correctly, then the setting you want to disable is called
"Require server verification (https:) for all sites in this zone" - that setting is done per Security zone. The setting is found in the Internet Options, Security tab, select the zone either Local intranet or Trusted sites, click the Sites button, and then clear the checkbox. You may also have to add the specific site that you want to control into the list of Local intranet or Trusted sites, respectively. I did a quick search and found a site with some step-by-step screen captures: surfthenetsafely.com/ieseczone7.htm. This one is for IE7, but the steps are identical except for the launching of Internet Options. In IE9 and later you click the thing that looks like a gear in the top right corner of IE, which is a menu, then you can click Internet options.
The site is not a trusted site. Does it need to be to install a certificate?
