QProcess: finished() signal not emitted running Powershell script

[ChrisW67]

Take a look at the console output from your program at run time and/or the return value from connect(). It is likely that you are receiving warning that QProcess does not have a signal matching "finished(int)" and that connect() returns false (Qt4) or a QMetaObject::Connection that evaluates as false (Qt5). The signal is QProcess::finished(int exitCode, QProcess::ExitStatus exitStatus)
