System Requirements for CyberVNC Remote Desktop Software.


CyberVNC can work on your PC and here is the minimal recommended hardware:


Each server (physical or virtual ones) can potentially handle up to 50 concurrent users. For over 50 concurrent sessions, we recommend using a farm of servers with the Load Balancing feature available in CyberVNC Enterprise Edition (Remote Access).

Note: The exact specifications of your hardware will depend on what kind of resources (CPU/RAM/Disk) your applications consume.


Your server must use one of the operating systems below:

  • Windows 7 Service Pack 1
  • Windows 8/8.1
  • Windows 10 Pro
  • Windows 11 Pro
  • Windows Server 2008 R2 Service Pack 1
  • Windows Server 2012 or 2012 R2
  • Windows Server 2016
  • Windows Server 2019
  • Windows Server 2022

32 and 64 bit operating systems are supported.

The required framework is .NET version 4.5.2 for all supported Windows versions.

  • If you install Remote Access on a Windows Server OS make sure the RDS/Terminal Services and RDS/Terminal Services Licensing roles are not installed before installing CyberVNC Remote Access.
    If these roles are currently installed, remove them and reboot.
  • Windows Home Editions are not supported.
  • On Windows Server 2016, 15 sessions maximum are allowed for Remote Desktop access.
