Remarks

MsiSetFeatureAttributes must be called after CostInitialize action and before CostFinalize action. The function returns ERROR_FUNCTION_FAILED if called at any other time.

The INSTALLFEATUREATTRIBUTE_FAVORLOCAL, INSTALLFEATUREATTRIBUTE_FAVORSOURCE, and INSTALLFEATUREATTRIBUTE_FOLLOWPARENT flags are mutually exclusive. Only one of these bits can be set for any feature. If more than one of these flags is set, the behavior of that feature is undefined.

See Calling Database Functions From Programs.

Note

The msiquery.h header defines MsiSetFeatureAttributes as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
