LiteStep requires only that you are running a 32bit version of Windows:
– Windows 95, Windows 98(se), Windows ME, Windows 2000, Windows XP, Windows 2003
NOTE: Windows Vista/2008 32bit versions are *NOT* supported in 0.24.8 !
Please check our website for experimental builds containing support for running under both 32bit and 64bit Windows XP/Vista/2008/Win7 versions. LiteStep is designed to consume less resources than the Explorer shell which it replaces; so there are no system requirements above and beyond that which is needed for a normal Windows-based system.
However, depending on what modules (add-ons) are loaded, any given desktop environment will have its own system requirements. This may range from being only compatible with Win2K/XP or requiring a 3d accelerated graphics card. Be sure to read the accompanying documentation for any theme or module that you choose to install.
