Distance on CD

The Distance 6 installation package is quite large (~32MB). To speed downloading, we have created two identical download sites: one in the UK and one in the USA. However, the size of the package may still pose some problems for people with slow or unreliable internet links. If you have difficulty downloading the program we can arrange to send you a CD. A nominal charge is made, payable in advance, to cover our costs. To order the Distance CD, please fill in and post us the order form.
