If you have a vision impaired person who wants to play solitaire then ditch Windows and Install a Gnome Desktop based Linux distribution (Ubuntu, Fedora etc).
The cards in the Windows version of Solitaire are tiny. However the cards in the AisleRiot Solitaire in Gnome enlarge with the application window so their size limit depends on your monitor.
