Certain files, such as text files and source files, do not carry version numbers. Therefore, the Windows Installer-based update must use another method to verify newer files. This method uses a hash for all non-versioned files. For non-versioned files, the file hash of the file on the computer is compared with the file hash that is recorded in the Windows Installer database. If a difference is detected between these two file hashes, Setup tries to fetch the file from the source installation media.
The "/addsource" command-line optionIf you are trying to deploy an update to lots of computers on which this issue may occur, we recommend that you first use the /addsource command-line option if this option is available.
