Compatible Operating Systems

VTScada Compatible OS Table

VTScada runs on Windows® 10 IoT Enterprise but not on IoT Core.
Note: VTScada versions 11.1, 11.2, and 11.3 support the Windows 10® operating system.

For VTScada Thin Clients

All VTScada Thin Clients require:

  • A network connection to at least one installed VTScada License to act as the server.
  • One or more concurrent VTScada Thin Client licenses.
From Windows PCs and Laptops
Launch the VTScada Internet Client (VIC) from computers running Windows Server 2003 or newer (no VTScada installation required).

  • Launch using Internet Explorer (ensure ActiveX is enabled) using a web address (URL).
  • Launch from your desktop using a small program downloaded once from your VTScada server via any browser.
From other Operating Systems
To launch the VTScada Anywhere Clients, we recommend the latest version of the following HTML5-compliant web browsers:

  • Safari® (OS X, iOS)
  • Chrome® (Windows®, iOS®, Android®)

Other HTML5-compliant browsers:

  • Microsoft Edge® (Windows®)
  • Opera® (Windows®, iOS®, Android®)
  • Firefox® (Windows®, iOS®, Android®)

Recommended Modems

Please see our Recommended Modems page for more info.

Please Note

  • NetDDE is not available on Windows Vista and higher. (It was removed in XP Service Pack II)
  • VTScada 10 and higher uses IANA registered TCP/IP port 5780 (not 1160). Configure firewalls to route RPC traffic accordingly.
  • When reusing internal modems or sound cards ensure that new computers have the correct motherboard slots.
  • Ensure 3rd-party software used with VTScada (e.g. accounting, reporting) is compatible with new OS.
  • When using virtual servers; never clone a computer after installing VTScada to make another virtual image (this leads to repository issues since both computers will have the same machine GUID in the registry)
  1. Server 2008 computers often require speakers or audio cards for some Alarm Notification functionality. Manual modem configuration may be required.
  2. Windows has discontinued support for XP® and Server 2003®.
