Installing a Missing Component

[This is preliminary documentation and subject to change.]

If the MsiGetComponentPath function was successful, the key file is present, and the missing file must be a non-key file. Since Microsoft® Windows® installer installs features, not components, the installer resolves which component the file belongs to and installs the feature that requires the least disk space.

If the MsiGetComponentPath function unexpectedly fails, you must install missing components. The following steps describe how to install missing components:

    To install a missing component

• Call the MsiInstallMissingComponent function if the feature associated with the component is unknown.

  Or

  Call the MsiConfigureFeature or MsiProvideComponent function if the feature associated with the component is known.

• Call MsiInstallMissingFile if an application is unable to open a file.
