Name	Version	Architecture	OS	Remark
UltraVNC Server	1.4.3.6	x64	Windows
	1.3.4	x64	Windows
	1.3.2a	x64	Windows	Doesn’t work with webVNC, because of a bug in UltraVNC. Alternatively, you can use the SSC TunnelClient with a separate VNC client, e.g. RealVNC Viewer 6.21.406.
	1.2.4.0	x64	Windows
RealVNC Server	6.7.2	x64	Windows	There seems to be a bug with the current noVNC lib v1.4.0.
TigerVNC Server	1.13.1	x64	Windows
		x64	Windows
X11VNC Server	2.8.84	x64	Linux
