The help you are getting from others is probably more relevant to your questions than anything I have to say.

However, I want to comment about your point 3: "Deploy [the executable?] ... just after the midnight backup".

You can really deploy the executable at any moment, not only at midnight. It is sometimes quite akward to have to wait until next midnight.

If you are interested, what you have to do is give your executables names like App_0001.exe, App_0002.exe, etc. Each version receives the next available number.

A loader program, for which you provide your users with a shortcut, will automatically load the latest version.

As an added bonus, you can have a different version of the loader program, which allows the users to choose an older version. In case the programmer messed up the latest version, the user can go back one or two versions, while emergency repairs are made. These emergency repairs are now no longer so urgent.
