That specific download was changing the .EXE which may be different per user account on Windows, which it shouldn't be, but that's the only thing I can come up with.
I see... I noticed another redundant download. When I download the update, it always switches the game into default English. When I switch it back to my language, it starts downloading again the large file and then, after two downloads, I finally have an updated version. When we need to do this twice for myself and my wife, it becomes really boring and time consuming
