FAIRMEADOW I had an early version of ReadIris 11. So early that it never actually worked. All contact with their support regarding how to update this to a later maintenance release of RI 11 were ignored, apart from one response that told me to use the check for updates menu item - which was missing from that version.
Nevertheless (after all, lightening doesn't strike twice, does it?), I went for the upgrade to 12. I bought on-line, and got the download. But nowhere was there a serial number, so I couldn't run it. Sent a mail, but no response. Suddenly a disc arrived by courier (no, I'd only ordered the download version!). Lots of paperwork, but still no serial number. Write again to Iris, and this time an answer - an apology and a serial number. Wonderful, except that the serial number was rejected as invalid. I replied, and was asked whether it was serial number or key I wanted. I sent the screenshot confirming that it asked for a serial number.
Despite several further e-mails to them I've had nothing further. I guess it's getting close to time to consider a legal approach.
