I bought myself a new reader today and installed on the virgin device the one-click install package, it took me a long time, I had to read all 23 pages, here's my tutorial for dummies like myself - it worked
for my old ebook reader I used the old fmon launcher that's no longer recommended. I'm still trying to figure out how to decrease the font for the KoReader menues on the new 7,8" reader and how to get rid of Nickel's book recommendations on the home page
