Lightning Express was a screen magnifier supplied by Claro Software and Sensory Software. It is no longer available from us but we do receive enquiries about it.
To help anyone who wants it, here is a link to the executable. It must be downloaded and run every day that you want to use it. We do not support it, we do not warrant that it works, and we will not undertake any more work on it. We recommend users try out either the new improved Windows Magnifier free in Windows 10 or another commercial solution. You may also find this guide to using your computer with some sight useful.
