The DIALux tool icon is missing in the Electrical Analysis task. We are planning to do lighting calculation in DIALux through AECOsim, so we installed DIALux on our PC. In the first picture below you can see that under Light Analysis tool bar both Visual and RELUX are shown, but in the list view it shows DIALux as well. After enabling all three DIALux still is not shown in my tool bar.
Note that I am using the delivered US Template dataset.
The DIALux option is only available in the SELECTseries6 NM and UK datasets. You can download these datasets from the Softwares Download site at:
