COMPADDSOURCE property

  • Artikkeli

The value of the COMPADDSOURCE property is a list of component GUIDs from the ComponentId column of the Component table, delimited by commas, that are to be installed to run from the source media. The installer uses this value to determine which features are set to be installed to run from source, based on the specified components. For each listed component ID, the installer examines all features linked (through the FeatureComponents table) to that component, and installs the feature that requires the least amount of disk space to install. The components listed must be present in the Component column of the Component table.

Remarks

Note that the component names are case-sensitive. Also note that if the LocalOnly bit flag is set in the Attributes column of the Component table for a component, then the component is installed to run locally.

The installer always evaluates the following properties in the following order:

  1. ADDLOCAL
  2. REMOVE
  3. ADDSOURCE
  4. ADDDEFAULT
  5. REINSTALL
  6. ADVERTISE
  7. COMPADDLOCAL
  8. COMPADDSOURCE
  9. COMPADDDEFAULT
  10. FILEADDLOCAL
  11. FILEADDSOURCE
  12. FILEADDDEFAULT

For example, if the command line specifies: ADDLOCAL=ALL, ADDSOURCE = MyFeature, all the features are first set to run-local and then MyFeature is set to run-from-source. If the command line is: ADDSOURCE=ALL, ADDLOCAL=MyFeature, first MyFeature is set to run-local, and then when ADDSOURCE=ALL is evaluated, all features (including MyFeature) are reset to run-from-source.

The installer sets the Preselected property to a value of "1" during the resumption of a suspended installation or when any of the above properties are specified on the command line.
