QProcess : unable to start sis file

**javed_alam786** · 23rd August 2011, 16:43

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.

Qt Code:

Switch view

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

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

To copy to clipboard, switch view to plain text mode

Just added code to trap error returned by QProcsess

I got QProcess::FailedToStart

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

Kind Regards,
Javed

Hi All,

I need to run SIS file on handset (Nokia E52) through code. Think of this as an auto updater app that downloads the latest version of target app and installs it automatically.

Please direct.

You can "bump" the same thread if you want to revive it.
No need to post a new thread.
If you are not getting any answers, then no one knows the answer...
Bumping the thread after a day or two might help, but if over longer time no one responds, then no one knows the answer (or maybe your question isn't clear enough)
