How to install and connect to TightVNC on Windows using bVNC

This guide is for configuring Windows for usage with bVNC Secure/Free bVNC Secure, but is completely applicable to any VNC client. Only the VNC client configuration would be different.

Please keep in mind that VNC authentication is inherently insecure, because it only allows passwords of up to 8 characters in length. Also, traffic between the VNC client and server is not encrypted and your data is vulnerable to spying. To solve both of these problems bVNC Secure supports tunneling your VNC connection over SSH for enterprise-level security of both your authentication credentials and data. If you are concerned with security and privacy, follow my guide for Windows on tunneling VNC over SSH with bVNC.

bVNC Secure is an Android and Blackberry Playbook/OS 10 application, available on Google Play and App World respectively. Find it on your mobile device or here:

Google Play, for devices running Android 2.2 and up, or here:

App World for BB Playbook and OS 10 devices.


0) Install TightVNC
- Go to: http://www.tightvnc.com/download.php
- Get and install the "Self-installing package for Windows".
- Do a default install and set a (VNC password)** and a control
interface administrative password (up to 8 characters).
- Click on the icon with the "V" in the notification area of the taskbar.
- Disable "Serve Java Viewer to Web clients"
- After you have it working you can look through for any other
settings you want.

1) Configure bVNC Client:
- Start bVNC
- Ensure "Connection Type" is set to "Basic VNC"
- Optionally name the connection something in Nickname
- Type the IP or hostname of the computer you configured in the first step.
- Type the (VNC password)** you chose from the first step in VNC Auth.
- You will probably have to check "Local mouse pointer", because TightVNC doesn't show a mouse pointer in Windows with bVNC.
- Tap "Connect", and you should be in.

    1. Hi Andrei, This was probably a problem with Google Play itself. Have you been able to download it since then?

  2. HI. I got this message on my BBerry playbook:
    "Error! Connection failed! Too many security failures"

    I setup TightVNC on my Windows 7 running PC and bVNC apps on my BBerry pbook. Connection type chosen was plain VNC.

  8. I have bought your software recently and my only complaint is that in the "Input Modes" the "Tap" makes a confusion with the "Swype". Let me explain... for example, I can do a middle-click following your help (tap-hold and tap with two more fingers), or simply sliding three finger quickly on the screen. That makes a conflict with another software I have, like "GMD Gestures Control" witch makes some shortcuts by gestures. Is that a way for you to help me? Edit: I have noticed that if we click on the BACK button, a left-click happens. Ps.: My tablet is a Samsung Tab 2 P3100 4.1.2

    1. Sounds like your tablet is not on the same network as the system running the VNC server... Whatever the cause, it's a network-level lack of connectivity.

  11. Hello mate. I've installed TightVNC on my Windows 8 machine and bVNC on my Blackberry Tablet. I'm entering the correct IP and password but when I try to connect it gives me this weird error: Address family not supported by protocol family. I'm not sure what's wrong?

  12. Hello Iordan,
    I installed VNC free service on my laptop running Win8 and tVNC on my Galaxy Note II phone.
    I do not have a V in my taskbar, so I cannot Disable "Serve Java Viewer to Web clients".
    When trying to connect I get an error: "connection failed: EHOSTUNREACH (no route to host)" on my phone.
    I try to rebooth both devices but it did not help.
    Can you help me please?
