Class not registered

I've been following the quickstart guide.

All works fine until I get to the complete-challenge step:

PS` C:\vault2> Complete-ACMEChallenge -IdentifierRef home -ChallengeType http-01 -Handler iis -HandlerParameters @{ WebSiteRef = 'MyExampleSite' }
Complete-ACMEChallenge : Retrieving the COM class factory for component with CLSID
{2B72133B-3F5B-4602-8952-803546CE3344} failed due to the following error: 80040154 Class not registered (Exception
from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).
At line:1 char:1

• Complete-ACMEChallenge -IdentifierRef home -ChallengeType http-01 -Ha ...

•   + CategoryInfo          : NotSpecified: (:) [Complete-ACMEChallenge], COMException
    + FullyQualifiedErrorId : System.Runtime.InteropServices.COMException,ACMESharp.POSH.CompleteChallenge
  
  

Now, having no experience with powershell this is more than a little hard to debug. And nowhere in the user guide is a problem like this mentioned. Google seems to think that either a component is missing or unregistered.

I'd like some help with this issue, but even more than that the error output of this and all the acmesharp programs could really use work.
