Hi all, forgive me for asking but are there any instructions for installing this on linux? the reason for the questionis that I have been running express invoice on suse 10.3 for a few months and have now upgraded to suse 11.0, I am sure when I installed it last time, I just clicked on the file and it self installed. I cant seem to get it to install this time and try as I might, I cant find any instructions for instalation. thanks in advance for pointing me in the right direction. Nigel.
