I thought I was out of the woods and could proceed with my installation. I thought by selecting a different license type that the error might go away, but every license type I selected resulted in the same error message over and over.Īfter I wasn’t getting anywhere, I called Microsoft Volume Licensing technical support and was able to convert the license to a Retail License, which then allowed me to install the license without getting an error. The error I received was, “A required registry key is empty.” After doing some research and digging through Microsoft KB articles, I couldn’t find any pertinent solution that resolved the error message.

I had my agreement number, but none of the installation options seemed to work for me.

I was attempting to install Open Value RDS CALs from Microsoft and received a peculiar error message while trying to apply the licenses. Everything was going very smoothly, until I got to the Terminal Server Licensing configuration. I was recently tasked with building a new Windows Server 2022 Terminal Server for a client.
