Advanced Value Lookup
Advanced Value Lookup shows contextual information for MSI column values, so you can understand references, paths, and types without looking them up elsewhere.

Supported lookups
| Context | What Master Packager shows |
|---|---|
Directory_ columns | The related key name, resolved MSI path, and resolved disk path. |
CustomAction table Type column | The numeric value and the corresponding custom action type name. |
Directory values
In columns such as Directory_, Master Packager resolves the referenced path so you can see where a file or component is installed.

Custom action types
In the CustomAction table, the Type column stores numeric values that represent specific custom action types. Master Packager shows both the numeric value and the matching type name, so you do not need to decode it manually.
