Thanks for getting back to me,

Just so I understand you right, here's what i've done. (Still not running my application :S)

w/o changing working directory
Qt Code:
  1. QString rx_path = QCoreApplication::applicationDirPath();
  2. QString command = ". " + rx_path + "/applications/bin/application";
  3. rx_process = new QProcess;
  4. rx_process->start(command,QStringList() << "-udp" << "42003");
To copy to clipboard, switch view to plain text mode 

w/ changing working directory
Qt Code:
  1. QString rx_path = QCoreApplication::applicationDirPath();
  2. QString command = "./application";
  3. rx_process = new QProcess;
  4. rx_process->setWorkingDirectory(rx+path + "/applications/bin/");
  5. rx_process->start(command,QStringList() << "-udp" << "42003");
