Dialux 3.14 May 2026

  • Geometry creation
  • Add luminaires and sensors
  • Define surfaces & materials
  • Set calculation parameters
  • Run calculations
  • Visualize & refine
  • Report & export
  • Disable Antivirus Real-Time Scanning (temporarily). The 3.14 installer uses an old copy protection driver that modern Windows Defender may flag as a false positive (it is not malware, just obsolete).
  • Installation Path: Do not install in C:\Program Files (UAC issues). Instead, install to C:\DIALux314 or a custom folder on the root.
  • Post-Install: Run the software. Go to Extras -> Settings -> Graphics. Set the OpenGL to "Software Rendering" if you see black viewports. Modern GPUs often conflict with the old renderer.

    • DIALux 3.14 (circa 2012-2015) was the swan song of the original codebase. Version 4.0 (later renamed "evo") was already in development. DIALux 3.14 represents the peak of CAD-based, calculation-first design.
