In the support portal where customers post tickets, there is no product entry for the Domino Administrator Client, but there is one for the Notes client and the Domino Designer. Please add Administrator Client to the list of products when creating a ticket in the HCL support portal.
This is also true for the support discussion forum.
It was suggested by HCL that they view the Domino Designer and Administrator Client as the same product. If you insist the customers cannot have Admin Client in the list, as an alternative, please change the entry from "HCL Domino Designer" to "HCL Domino Administrator and Designer Clients"
