Technical specifications
Shadows is developed primarily for Windows 11/10 and is compatible with Windows 8.x, Windows 7 and Windows Vista. It requires a 64-bit Windows (compiled for x64, not ARM). Older versions of Windows are not compatible anymore with Shadows.
Shadows can run on Mac OS with older Mac with Intel processors, using a Windows emulator (Parallels Desktop, VM Ware or Wine). More recent Mac with Apple Silicon processors (M1 to M5) can run Shadows on Windows 11 ARM with Parallels Desktop 20+ or VM Ware Fusion. In both cases, the application may be slower and may have a few bugs. Users using these platforms are encouraged to share their feedback with us.
It is recommended to have at least 8 GB of RAM. 3D visualizations require a graphic board compatible with OpenGL version 3.3 minimum. Shadows uses some files that are copied in the "Documents\Shadows Data" folder. This folder must not be located over a network or in the cloud. Always check the compatibility on your platform by installing the freeware version. If the freeware works fine, then Shadows Expert and Shadows Pro will work.
The user interface of Shadows is translated in 18 languages: English, French, German, Italian, Spanish, Portuguese, Greek, Brazilian, Dutch, Hungarian, Slovenian, Polish, Czech, Arabic, Catalan, Russian, Romanian, Persian. View the translation status
