Now, before you do your upgrade, have a look at the file's modified and creation dates. If they match, then MSI takes that as a signal that they can be overwritten (because it sets those dates to the same value during install). It can also, optionally, do a hash check. If a user has modified the file, then the dates should be different and MSI will leave the file alone. So the question is whether the file would be modified post installation? If so, then you would need to look at a verbose upgrade log for further details.
