Thank you all for thinking. Yes, it is Janome Digitiser Jr, version 3 which ran beautifully on Win7 and has been asked to go to Win10 (OH says Win 7 is not secure on the internet so he bought me a new Win 10 machine. He wants to upgrade the old one to 10 as well, so it will be useful) When I run the DVD I get an error code about a HASP file. And it wants an updated dongle. I thought that anyone else who had the software would recognise the question!
@wrenkins, the dvd might well end up out of the window, but I will keep the Janome 350e.
