You are most welcome :)
The exe you are trying to update. is it your own program? -
@mrjj yes

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
-
@mrjj Qt installer framework can replace a running exe and dll I don't know how!

well on windows its not so hard using windows API. -
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 :) -
@SGaist
