Just stopped by to say thanks...

...to the devs and maintainers of this excellent piece of software. The amd64.deb package installed with a simple dpkg -i with no fuss both in a very old machine (still running Ubuntu 18.04) and a very up-to-date one (running Devuan 6 Excalibur) and worked perfectly in both of them, allowing me to escape the sucky Windows app the lab supplied on the CD. Thank you all very much! 👍
