Getting com_dotnet error during Server Configuration

Greetings. I have the WebIssues server up and running. During initial configuration, I am attempting to establish the connection to the MS SQL Server that will host the DB. when I hit "Next" I am getting the error - The 'com_dotnet' extension is missing or disabled. I see an issue in these forums where this was address with a beta release that was missing a break in the setup script, but find nothing that addresses this particular scenario. What is this error message telling me? What do I need to do to resolve it?
