I have component that consist of one *.sys file (with version). This file is also marked as key file for this component. I received requirement in new version of our product to install this file into the new location - so I've changed its Destination.
Clean install works fine. Problem is on minor upgrade. Version of sys file itself was not changed, only its location. When installer check if this file should be installed it checks two versions - of file on the old location and of file on the CD. They are equal, so installer does not copies file into the new location
Old location is C:\Program Files\FilesX\XpressRestore\Xpress Client\
New location is [SystemFolder]drivers
Here are relevant lines from verbose log:
