Hello @bryant,
I have seen that before, you might need to run the Post_installation steps from the SAS Deployment Wizard in your depot.
If this does not help, you might need to open a ticket with SAS Technical Support.
BTW if the SDM cannot fin the hotfix, or it is either because you need to select its location, or it is not in the right version for your installation, or it is already installed in your system
Kind regards,
Juan
