Error message when signing up for payment services in NAV 2009 R2

I’m trying to get payment services set up in NAV 2009 R2. According to the instructions on this website I’m suppose to select Function -->Sign Up Now from the Payment Services Connection Setup screen. When I do that this is the error that I’m getting …

This message is for C/AL programmers:

Could not create an instance of the OLE control or Automation server identified by GUID={DAB99883-91F-4CEA-86A1-58EFE34D77A0} 1.0:…Unknown Automation SErver.Unknown Class. Check that the OLE control or Automation server is currently installed or registered.

Is anyone familiar with this error?
