Specifies the component code.
Defines the installation mode. This parameter can be one of the values shown in the following table.
Provides the component path, performing any installation, if necessary.
Provides the component path only if the feature exists; otherwise, returns an empty string. This mode verifies the existence of the component's key file.
Provides the component path only if the feature exists. Otherwise, returns an empty string. This mode checks the component's registration but does not verify the existence of the component's key file.

- combination of the msiReinstallMode flags
Calls ReinstallFeature to reinstall the feature using this parameter for the ReinstallMode parameter, and then provides the component.
This method does not return a value.
The ProvideComponent method combines the functionality of UseFeature, ConfigureFeature, and ComponentPath. The ProvideComponent method simplifies the calling sequence, but it also increments the usage count and should be used with caution to prevent inaccurate usage counts. The ProvideComponent method also provides less flexibility than a series of individual calls to the methods and properties previously mentioned.
If the application is recovering from an unexpected situation, the application has probably already called UseFeature and incremented the usage count. In this case, the application should avoid incrementing the usage count by calling the ConfigureFeature method instead of the ProvideComponent method.
The msiInstallModeExisting option cannot be used in combination with msiReinstallMode flags.
