Which version of Windows do you need?

1. Lumion 11 and newer:

Lumion 11 and newer requires Windows 10 or Windows 11.

Note:

  • Lumion 2023 and newer requires Windows 10 version 2004 or newer, or preferably, Windows 11 version 21H2 (Build 22000) or newer.
  • Lumion 11 and 12 require at least Windows 10 version 1809 in order to run.

Important:
Insider Preview builds of Windows are pre-release versions that are intended for testing only and can be unstable. They are not recommended for use as a primary operating system and are not guaranteed to work with Lumion.

To see which version of Windows 10 or Windows 11 you currently have installed, click on the Windows button and select Settings -> System -> About, to see the version number.

 

2. Lumion 11 and older:

Lumion 10.5.1.2 and older versions are no longer supported, however, they should, in principle run on Windows 10 and newer.

If you're using Lumion 6.3 or older and need more than 4 GB of memory for your Projects, we recommend that you run Lumion on Windows 7 (64-bit with at least SP1).

The reason is that Windows 8 and 10 do not allow older DirectX 9 applications (such as Lumion 6.3 and older) to use more than 4 GB graphics card memory for a given application - and no system memory either. On Windows 7, graphics card memory and system memory are not limited by the 4 GB cap when running older DirectX 9 applications such as Lumion 1.0-6.3.

Lumion 6.5 and newer are not affected by this cap and can use more than 4 GB memory on Windows 7, 8 and 10.
