File Versioning Rules When Neither Components Has a Key File
I understand that the Windows Installer uses key files to compare the version, date, and language of components and determine whether to update the component on target machine.
My question is that how does the installer determine whether the component needs to be updated if neither components has a key file set?
Another question of mine is that with no key file set to both components, but with a file whose Modified date is later than the Create date on the target computer, does it not install the file? I know that the File Versioning Rules consider Nonversioned Files as User Data so it does not install the file, but with no key files, I wonder how the installer determines whether to install.
