| 17 * thus can not be used to elevate the Process. | |
| 18 * | |
| 19 * On Windows this class uses ShellExecuteExW to control | |
| 20 * the child process. On Linux systems QProcess is used. | |
| 21 * | |
| 22 * It subclasses QThread so the installation can be done | |
| 23 * asynchronusly. */ | |
