If you try to upgrade from a version of the Configuration Manager console that has the Traditional Chinese (Hong Kong) language pack installed to an installation of Configuration Manager (Current Branch v1606) that does not have that language pack installed, the upgrade may fail with the following error message:
Internal Error 2711. LP3076
