Microsoft Virtual Machine Converter (MVMC) - "The Certificate With Thumbprint was not found in the personal certificate store"

Recently, I've been testing the Microsoft Virtual Machine Converter 3.0/3.1 product to push VMs up to Azure.   Upon entering the Subscription ID and Cert Thumbprint, I would get the following error:

"The Certificate With Thumbprint <thumbprint> was not found in the personal certificate store"

I used the typical method of creating a Azure management cert (makecert - in Windows SDK)

makecert -sky exchange -r -n "CN=MyCert" -pe -a sha1 -len 2048 -ss My "MyCert.cer"

 

Turn out, I had the cert in the my personal store, but it needed to be imported into Trusted Root Certification Authorites:

Instructions on Exporting and Importing the cert into the appropriate folder is located in the following Microsoft KB:
