View Full Version : SIS Install through App

23rd August 2011, 14:04
Hi All,

I am trying to install an app through an updater app on my Nokia E52 handset.

Updater application is basically checks for new version and donwloads the SIS file. I want to install this downloaded SIS file when user clicks on 'Install Updates' button.

I have tried QProccess.Start() but it does not do anything.

qStartIntall = new QProcess(this);
qStartIntall->start("C:\\Data\\DOWNLOADED_APP.sis", QIODevice::ReadWrite);

Please give direction or code or example ......... anything please.

Kind Regards,
