Windows SmartScreen will flag this as unrecognized since it's an unsigned free tool; click More info → Run anyway. Download here: https://github.com/Forrest-Develop/TightVNC-url-Launcher/releases/download/v3.0.0/TightVncLauncher.exe

WHAT THIS IS

TightVNC Launcher makes vnc:// links in your browser open TightVNC Viewer automatically, with the password pre-filled if one is provided by the site. It is used alongside the internal inventory management site to connect to managed devices from the asset detail page ("Open with TightVNC" button), but it works with any website that generates vnc:// links.

No administrator rights are required to install or uninstall.

REQUIREMENTS

TightVNC Viewer (tvnviewer.exe) must already be installed on this computer before clicking any vnc:// links. Download it from https://www.tightvnc.com/download.php and install the "Viewer Only" option if you don't need the server component.

SETUP (do this once)

1. Double-click TightVncLauncher.exe.
2. A setup prompt will appear — click Yes to install.
3. The launcher copies itself to your user profile and registers the vnc:// protocol for your Windows account. That's it.

After setup, clicking any vnc:// link in your browser will open TightVNC Viewer directly. If tvnviewer.exe isn't found automatically the first time, you'll be asked to browse to it once — that path is then remembered for all future links.

To uninstall: double-click TightVncLauncher.exe again and choose No when asked to reinstall.

THE .REG FILE (alternative / backup method)

TightVnc-Protocol.reg is a manual fallback only — the exe-based setup above is preferred and requires no editing. Only use the .reg file if the exe-based setup fails for some reason.

If you do use it:

1. Open TightVnc-Protocol.reg in Notepad.
2. Replace on the last line with your actual Windows username (e.g. C:\Users\jsmith\AppData...).
3. Double-click the file and confirm the registry import.
4. Manually copy TightVncLauncher.exe to: C:\Users<YourUsername>\AppData\Local\TightVncLauncher\TightVncLauncher.exe

VNC:// LINK FORMAT

The launcher accepts the following URL format:

Basic (no password — TightVNC Viewer will prompt for one): vnc://192.168.1.10

With port (defaults to 5900 if omitted): vnc://192.168.1.10:5900

With auto-filled password (inventory site only — see note below): vnc://192.168.1.10?p=

The ?p= parameter carries an AES-256-GCM encrypted password specific to the inventory management site (lib/vnc-link-crypto.ts). Plain vnc://host links without ?p= work with any website or application that generates standard vnc:// URLs — TightVNC Viewer's normal authentication dialog will appear instead.
