InstallShield 2019 » InstallScript Language Reference
Project • This information applies to InstallScript projects.
The FeaturePatch function is called only in installations that use differential media. (You can check the media format by calling MediaGetData with MEDIA_FIELD_MEDIA_FLAGS as its second argument).
FeaturePatch causes the next call to FeatureTransferData or FeatureMoveData to reinstall all features that are already installed when FeatureTransferData is called, including all of the maintenance/uninstallation feature’s files except for Data1.hdr, Data1.cab, and Layout.bin. (Note that the maintenance/uninstallation feature is automatically placed in your disk image by the release builder and is not displayed in InstallShield.) A copy of the running file media library is stored on the target machine for use during subsequent maintenance operations, that is, modifying, repairing, or uninstalling.
