Known issue when launching VNC Server in Windows 10/11

Follow

We are aware of an issue currently affecting some Windows 10/11 users where the VNC Server process fails shortly after launching; the VNC icon also fails to show in the system tray. If you experience this, you can check the Event Viewer in Windows - searching for "VNC Server" - to find the exact error code. It should look similar to this:

 

Faulting application name: vncserver.exe, version: 6.10.0.47347, time stamp: <xxxxxx>
Faulting module name: vncserver.exe, version: 6.10.0.47347, time stamp: <xxxxxx>
Exception code: 0xc0000409
Fault offset: 0x0000000000432695
Faulting process id: 0x16cc
Faulting application start time: <xxxxxxxxxx>
Faulting application path: C:\Program Files\RealVNC\VNC Server\vncserver.exe
Faulting module path: C:\Program Files\RealVNC\VNC Server\vncserver.exe

 

A discovered workaround for now is to disable the printing function which should resolve this while our development team work on a resolution for it. You can disable printing by following these steps:

  1. Open Registry Editor
  2. Navigate to the key HKEY_LOCAL_MACHINE\Software\RealVNC\vncserver
  3. Create a new String value named EnableRemotePrinting
  4. Set it to a value of  0
  5. Try starting VNC Server again
