Manual fix via DBI:
What the error means
- NSP is a container of one or more NCA files plus ticket/metadata. Each NCA holds a specific content part (executable, patch, DLC, legal info).
- A ProgramType NCA (sometimes referred to as the "Program NCA" or the NCA with title metadata that indicates content type) is required so the system or installer can determine whether the package is a base game, update, DLC, or other content.
- The error indicates that the package you attempted to install is missing that specific NCA or that the NCA is malformed/corrupted and the ProgramType flag cannot be read.
- Program NCA: Contains the executable code, main game binaries, and startup logic.
- Control NCA: Contains metadata, icons, and language strings.
- Legal NCA: Contains licensing and legal information.
- Patch NCA (Update): Contains delta patches over the base game.
