    you're right, can't replace running exe, so I think the best way to update is write an another app for updation right?

    Well even another program cannot override the exe, so the updater must
    close the running version.

        You are most welcome :)

            Ok. that makes it easier to get it to close. :)
            Will user check for update from inside the program or how will that happen?
            (if i may ask)

              @mrjj When the app starts it checks for update if available-> ask for update permission(user) -> invoke the updater using QProcess -> as you said close the app -> download and replace the exe

              Pardon my English
              Thank you.

                    There is a link to an article that talks about this problem and possible solutions. http://www.catch22.net/tuts/self-deleting-executables on Windows.

                    I, personally, would try to keep this sane. A separate updating utility that closes the original program and replaces or removes whatever should be replaced or removed is probably the safest thing to do.

                      I completely agree!

                        Hi,

                        One possibility would be to use the Qt Installer Framework that, AFAIK, has an updating functionality

                          ;)
                          Do not worry
                          he is not planning on overwriting the exe from WITHIN the exe :)
                          Even @Rondogs link is pretty interesting,
                          it does indeed smell of a complex way of shooting your foot off :)
