MultiDigiMon -touch doesnt work with QProcess::startDetached("MultiDigiMon -touch");

Hello,

I'm trying to open MultiDigiMon.exe in Windows 10 in my QT App to configure touch screens.
I'm trying with

QProcess::startDetached("MultiDigiMon -touch");

It doesn't work, nothing happend. I tried to write on cmd.exe and it works. Any idea?

Thanks

You are using a relative path. Construct full path to the executable.
Also, use QProcess properly: command to execute and parameters are two diffrent parameters (see documentation).

QProcess::startDetached("MultiDigiMon", QstringList() <<  "-touch");

QstringList() << "-touch"

QProcess::startDetached("C:\\Windows\\System32\\MultiDigiMon.exe",  QStringList() <<  "-touch"); 

And it doesn't work

@JonexElectronic Then try with start() and connect a slot to https://doc.qt.io/qt-5/qprocess.html#errorOccurred to see what error you get.

I wrote the next code to get the error:

QProcess *ElProceso = new QProcess(this);

connect(ElProceso, SIGNAL(errorOccurred(QProcess::ProcessError)),this , SLOT (showError(QProcess::ProcessError)));
ElProceso->start("C:\\Windows\\System32\\MultiDigiMon.exe",  QStringList() <<  "-touch");

showError is a funtion that just show me the ProcessError.

The error returned is 0.

What I should do?

Hi
If you run C:\Windows\System32\MultiDigiMon.exe in a cmd prompt can the app start without showing a
UAC "allow this" dialog ?

@mrjj Hello, yes I can execute and no dialog are showed.
I think the problem is that I am running a QT 32 bit app on a WIN10 x64 OS. Based on this post :

But I found this post really interesting:
