Hi Jeri, the Lumion installation including all materials and models requires about 6GB of harddisk space - however, this will increase in Lumion 3.0 due to expanding asset libraries.
In addition, Lumion saves all scenes and imported models on the Windows partition in a hard-coded location (User/My Documents/Lumion 2).
If you make many scenes and import a lot of models, you will find that you're going to need a lot of space for that (unless you constantly moves scene/imported files that you aren't using). As an example, my Lumion 2 scene/library folders take up over 9GB.
On top of that comes the Windows 7 operating system which according to Microsoft requires something in the region of 20GB to be on the safe side.
