cd C:\setup\Appeon\AS4Cloud setup.exe /s
The icon indicating the installation progress will be minimized and displayed on the Windows Taskbar. When the installation is completed, the icon will vanish. To confirm that the installation is successful, go to the Windows Start menu, and make sure the Appeon for PowerBuilder 2015 | Appeon Server for Cloud shortcut menu is created; and then go and check this log file: C:\Windows\System32\AppeonInstallLog\AppeonCloudSilent2015.txt to determine if any error occurred during installation.
