QProcess DOS command not working

[TGRSM]

I'm trying to invoke the Windows On-Screen Keyboard with the command:

C:\Windows\System32\osk.exe

Running this command from DOS works perfectly fine.

But when I run from with the Qt application

int exitCode = QProcess::execute( "c:/Windows/System32/osk.exe");

The exit code is -2.

I have also tried to wrap this within a DOS bat script and execute this as follows:

int exitCode = QProcess::execute( "cmd /c \"w:/scripts/myscript.bat\"");

And myscript.bat has:

c:\Windows\System32\osk.exe

But this gives:

'c:\Windows\System32\osk.exe' is not recognized as an internal or external command, operable program or batch file.

This was asked a few weeks ago. Search the forum posts.

The upshot is you're trying to run a 32-bit from a 64-bit environment, or vice versa.

@TGRSM
Do not you need arguments to call execute?
int QProcess::execute(const QString &program, const QStringList &arguments)
https://doc.qt.io/qt-5.15/qprocess.html#execute

The following one is run like
QStringList arguments;
arguments << "/c"
<< ""w:/scripts/myscript.bat""
int exitCode = QProcess::execute( "cmd", arguments );
