Unlike VNC Connect or any other VNC-based tool, such as RealVNC, TightVNC, or UltraVNC, FixMe.IT guarantees a fast and stable connection in any environment, works through firewalls, and does not require enabling any additional ports, which makes it ideal for both external and internal remote support.This UltraVNC software can be used to display the screen of another computer (via internet or network) on your own screen. The Virtual Network Computing (VNC) application can be stored on and launched directly from your USB device (Portable VNC Viewer). UltraVNC Viewer is an Open Source VNC Viewer.
