LyX ⇒ Installation of new Document Class (icbo) in LyX 2.0.2

[diverzulu]

Hello All,

I need to install a new .cls file to be available as a new style in the LyX document configuration list. I've done this without any problem until 1.6 but not in 2.0 it just is not working.
I am using MikTeX 2.9 and have the proper icbo.cls file. The usual way I used to do it: create a directory under <miktex dir>/tex/latex, rebuild FNDB, reconfigure LyX, restart LyX; is not working in 2.0 !!
What can I do ?

Yours truly
