The first thing you need to do is read these two topics: * Aaron Stebner on file replacement : http://blogs.msdn.com/b/astebner/archive/2005/08/30/458295.aspx * MSDN docs: http://msdn.microsoft.com/en-us/library/aa368267(v=vs.85).aspx
If the files in question are versioned files (dlls and exes) then as long as the version numbers increase then by default will be replaced based on a highest-version-wins bases. This helps insure that you don't damage the system by installing an older version. If the files are unversioned, then the creation time and modification time are compared, and if they are different then the file has been edited since installation (as those two dates are synced up at installation time) and the file is considered user data which is not safe to overwrite (the user may have changed some settings which they want to keep, etc). You'll have to consider whether those rules are sufficient for your needs. If not, then you will need to look into the REINSTALLMODE (http://msdn.microsoft.com/en-gb/library/windows/desktop/aa371182(v=vs.85).aspx) property, possibly setting it to "amus" (which means replace all files regardless of versions or dates, and is generally not recommended).
