ADFS MFA Adapter fails when installed manually

Question

Dear experts,
When following the article on http://technet.microsoft.com/en-us/library/dn807157.aspx, my ADFS service cannot load the WindowsAzureMultiFactorAuthentication provider, eventid 105.
I used the 'Install the AD FS Adapter standalone using the Web Service SDK', with the edited config file using a username and password. When browsing to the SDK folder on my MFA server using IE from the ADFS server, I can login and use all SDK services normally
but ADFS fails. Installing MFA locally on the ADFS server fixes the issue, but manual configuration should be possbile according to the technet article.
Also, there is an error in the technet document, it says to 
Run the MultiFactorAuthenticationUserPortalSetup64.msi
But this should of course be the adapter MSI file.
Is there a fix?
Sincerely,
Jos

Thanks for the note on the typo. We'll fix the documentation on MSDN and the MFA Server help file.
For those having issues getting the adapter to work, we have had a couple of support cases escalated recently that both turned out to be typos in the config file. The registration script needs to have the correct path to the config file, and the config file
should look something like this:
<ConfigurationData xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <UseWebServiceSdk>true</UseWebServiceSdk>
    <WebServiceSdkUrl>https://server.domain.com/MultiFactorAuthWebServiceSdk/PfWsSdk.asmx</WebServiceSdkUrl>
    <WebServiceSdkUsername>domain\username</WebServiceSdkUsername>
    <WebServiceSdkPassword>password</WebServiceSdkPassword>
    <WebServiceSdkCertificateThumbprint></WebServiceSdkCertificateThumbprint>
</ConfigurationData>
From the ADFS server, you can copy the WebServiceSdkUrl into a web browser. You should be prompted for a username/password. Enter or copy/paste what you have in the config file. it should display the web service operations without any certificate warnings.
If there are warnings, you may have to import the certificate into the Trusted Root Certificate store so that the ADFS server trusts it.
