downloading and installing an external application within qt.

hello friends can anybody tell me how to write a program to download and install an external appplication within qt...............................thanks in advance:)

Your specification needs to be more precise.

For example, HOW do you want to install the program? Download the setup.exe and run it? Download a file to a specific place on a hd? Have a look at QHttp and QProcess.

Secondly, please don't duplicate your topics.
