But I wonder why I have two update exe files. One is Couatl_Updater2.exe and another is Couatl_Updater.exe Which one should I use? When I run one after another, they seem to do their own updates.
There is a reason why you put an icon on the Desktop ( pointing to the Couatl_updater.exe ), and it's precisely so you don't have to wonder which one to use.
If you haven't noticed the icon, or removed it, the one to use is always the Couatl_updater.exe, because the only thing it does, is being sure you have the latest version of the Couat_Updater2.exe (and if you haven't, it will download it), which is the one that makes the actual job. This way, the updater can "update itself".
