ERROR_UNKNOWN_FEATURE
ERROR_UNKNOWN_FEATURE means that Windows Installer could not find the requested feature identifier for the selected product. A feature is an MSI authoring identifier, not necessarily the product name shown in Apps and Features.
What to check
- Verify the ProductCode and the exact feature identifier supplied by the caller.
- Check that the operation is being performed against the intended installed product and user context.
- For package authors, inspect the Feature table rather than guessing an identifier from visible UI text.
