During a fresh install the following things are done:

  • Create installation directory (default: %Programfiles%\UltraVNC) and copy files to it.
  • Add shortcuts to start menu and desktop.
  • Associate .vnc with UltraVNC viewer by adding registry keys \\HKEY_CLASSES_ROOT\.vnc and \\HKEY_CLASSES_ROOT\VncViewer.Config.
