Installer.FileHash method
The FileHash method of the Installer Object takes the path to a file and returns a 128-bit hash of that file. The file hash information is returned as a Record Object. The entire 128-bit file hash is returned as four 32-bit IntegerData property fields.
The values returned in the Record Object correspond to the four fields of the MSIFILEHASHINFO structure returned by MsiGetFileHash. The numbering of four fields is 1-based in the MsiFileHash Table.
- Field 1 corresponds to the HashPart1 column.
- Field 2 corresponds to the HashPart2 column.
- Field 3 corresponds to the HashPart3 column.
- Field 4 corresponds to the HashPart4 column.
