these are the ones that also apear in the documents->settings menu, but where
are the rest?
MiKTeX tries at this point to download the missing document class arab-article from the Internet.
There was a bug in some older MiKTeX-versions where the configuration was stopped when there was no
open Internet connection.
So I recommend to update MiKTeX first, using its "Update Wizard" program which is available in
Windows Start menu under MiKTeX (open Internet connection is required). Then reconfigure LyX also
with open Internet connection.
When this doesn't help, reinstall LyX using this installer:
