application update

[enzeez]

Hello,

I need to provide an updater exe along with my product executable in setup.

My product exe will check for updates if any, available and will launch
a process , updater.exe.
updater.exe downloads the updated version available.
This updater.exe needs to replace the current product exe with the new
ones thats downloaded.

Can someone guide me how do i achieve this?

Is it ok to just replace or delete the current exe and create a new exe
with same name?

I am new to such a task and i need to know the best possible solution.

I dont want users to uninstall and install the new version.
However, uninstalling silently by the updater.exe and then the
downloaded setup.exe run by updater.exe is also acceptable - is this
possible?

Thanks in advance
NZ
