By far the easiest way to buy a DataView license is by credit card via the University of St Andrews online shop below.
A secure credit card payment facility is available.
I will be informed automatically by e-mail as soon as payment is made, but it is probably a good idea to contact me by e-mail before making payment, to check that I am able to respond quickly (not on holiday etc).
If you do not wish to pay by credit card, contact me to discuss alternative.
I will send you a license file that allows DataView to read commercial format files as soon as I receive notification of payment or upon receipt of an order. The file will be sent as an e-mail attachment, so make sure that you tell me the e-mail address to which the file should be sent.
