How many "digits" does Windows Installer check for executable files?
I know that Windows Installer checks only the first 3 "digits" of a version number for MSI's to determine if an MSI can upgrade over a previous one. That's for MSI's themselves.
Within the MSI, for the version numbers on binary executable files, .exe, .dll, and such, does it also still only check the first 3 "digits" of the version, or does it check all 4 "digits", when deciding if a versioned executable file is a newer version and to replace it or not during an upgrade?
(The "File Table" help topic describes the data type used for versioned files, and the "Version" help topic describes the xxxxx.xxxxx.xxxxx.xxxxx [each field ≤ 65535] format.)
