You're looking for information on downloading Dialux 4.13.0.2. Dialux is a software tool used for lighting design and calculations. Here's what I found:

Dialux evo 4.13.0.2

The version you're looking for seems to be an older version of Dialux evo, a software by ERCO. I couldn't find an official download link for this specific version, as the company might have removed it from their website.

However, I can guide you on where to look for it:

Official ERCO Website: You can try visiting the ERCO website (www.erco.com) and searching for "Dialux evo" in their software section. They might have an archive or a download page for older versions.
Software Archives: Websites like Internet Archive (archive.org) or Softonic (softonic.com) might have a copy of Dialux evo 4.13.0.2. Keep in mind that downloading software from third-party archives can pose security risks.
Contact ERCO Support: If you're unable to find the software through official channels, you can try contacting ERCO's customer support or technical team directly. They might be able to provide you with a download link or guidance on how to obtain the software.

Newer Alternatives

If you're looking for a more recent version of Dialux or similar software, you can explore:

Dialux evo 8: The latest version of Dialux evo is available on the ERCO website. It offers improved features and performance.
Other Lighting Design Software: You might consider alternative software tools for lighting design, such as AGi32, Relux, or IESVE.

Please ensure you have the necessary licenses or permissions to use the software, and be cautious when downloading from third-party sources to avoid any security risks.

Official support and direct downloads for DIALux 4.13.0.2 have been discontinued by the developer, DIAL GmbH. They strongly recommend using the modern successor, DIALux evo , which is the current industry standard.

However, if you specifically need version 4.13.0.2 to open legacy projects or for specific features like sports lighting that are handled differently in the new software, you can still find it through third-party archives and community links: Where to Download DIALux 4.13.0.2

Third-Party Software Archives: Sites like Uptodown and Filerox host older versions of DIALux, including 4.13.

Direct Community Links: A setup file for DIALux 4.13.0.2 is occasionally shared by users on the DIALux Community Forum or in resource lists from engineering firms like South-Eastern Electrics. Key Considerations for Older Versions

Compatibility: DIALux 4 was designed for older versions of Windows. While it may run on Windows 10/11, it is considered technically outdated and does not support modern BIM workflows.

Opening Old Projects in DIALux evo: You can often import older .dlx files into the 32-bit version of DIALux evo. To do this, navigate to your installation folder (typically C:\Program Files (x86)\DIAL GmbH) and run the 32-bit executable to find the import option.

Security: Always scan files from third-party sites with antivirus software before running the installer, as these are not official manufacturer links.

Key Features of Dialux 4.13.0.2

Classic Interface (SDI - Single Document Interface): Unlike the modern Ribbon-based UI of Dialux Evo, version 4.13.0.2 offers the classic drop-down menus and toolbars. Experienced users find this workflow significantly faster for repetitive tasks.
2D and 3D Viewports: Simultaneous 2D drafting and 3D visualization without the heavy resource demands of modern rendering engines.
Plug-in Compatibility: This version supports the vast library of ULD (User Luminaire Data) and plug-ins from manufacturers like Philips, Osram, Trilux, and Zumtobel, many of which are no longer compatible with Evo.
Lighting Calculation Core: Based on the robust radiosity method and supported by the CIE (International Commission on Illumination) standards. It provides accurate illuminance, glare rating (UGR), and color rendering calculations.
Street Lighting Module: A dedicated tool for road and tunnel lighting design that many engineers argue is still superior to its implementation in newer versions.
Freeware Status: Like all Dialux versions, 4.13.0.2 is completely free to use.

Method 3: Manufacturer CDs/DVDs

If you work for an electrical engineering firm, check old physical media. Manufacturers like ERCO, Louis Poulsen, and BEGA often included the full Dialux 4 installer on their product data CDs as late as 2016.

Installation & Setup Tips

Since this software was designed for older Windows versions, you might encounter permission issues on Windows 10/11. Follow these tips for a smooth installation:

Right-click the setup file and select "Run as Administrator."
If the installation fails, try running the installer in "Compatibility Mode" for Windows 7.
Language Packs: The installer usually defaults to English, but you can download language packs within the software settings if needed.
LDT Files: You will likely need to download photometric files (.ldt) manually from lighting manufacturer websites to use in the program, as the built-in plugin updater may no longer function correctly.

Common Problems and Fixes for Dialux 4.13.0.2 on New PCs

If you have successfully completed the Dialux 4.13.0.2 download but the software crashes or looks wrong, try these solutions:

Problem 1: "Runtime Error! Program C:...\DIALux.exe"

Cause: Corrupt graphics driver interaction.
Fix: Go to Start Menu > DIALux > Configuration > Set "Graphics Engine" to "OpenGL" instead of "DirectX." Restart.

Problem 2: The interface looks microscopic (4K monitor)

Cause: Windows DPI scaling.
Fix: Right-click DIALux.exe > Properties > Compatibility > Change high DPI settings > Check "Override high DPI scaling behavior" > Set to "System (Enhanced)."

Problem 3: Can't see 3D view (black screen)

Cause: Integrated Intel GPUs on Windows 10/11.
Fix: Force Dialux to run on the dedicated GPU (if available) via Windows Graphics Settings > Add an app > Choose "High performance."

Problem 4: Printing or PDF export fails

Cause: Legacy print engine.
Workaround: Do not print directly from Dialux 4. Instead, go to Output > Report > Export to HTML > Then open the HTML file in Chrome and print to PDF from there.

Q2: Can I install Dialux 4 and Dialux Evo on the same computer?

A: Yes. They use different registry keys and installation folders (Dialux 4 goes to Program Files (x86), Evo goes to Program Files or Users folders). They do not conflict.

3. Archival Projects

Many large infrastructure projects (airports, stadiums, factories) from the late 2000s to mid-2010s were saved in the .dpl format. Opening these in Evo often breaks layouts or loses data. Version 4.13.0.2 is required to edit legacy files.

Troubleshooting common issues

Installation fails: Ensure you have administrative rights, required .NET frameworks, and sufficient disk space.
Crashes or graphics glitches: Update GPU drivers, try compatibility mode, or reduce hardware acceleration in the application settings.
Missing photometric data: Re-download manufacturer libraries, or import IES/IESNA files directly via the photometric data manager.
Print/export problems: Install or update PDF/printer drivers; export images at lower resolutions if memory errors occur.
License or activation errors: Verify installer source; legacy versions usually didn’t require online activation, but manufacturer add-ons might.
