I'm writing a letter in LyX, and I want to choose a document class for it. (I don't like the default
Document -> Settings -> Document class, I see that most classes are "unavailable". For example,
Unavailable: Letter (KOMA-script). How do I make those available?
I tried installing the
koma-script package in the MiKTeX package manager, but it didn't help.
Here's the dialog I get when doing
LyX: System reconfiguration failed
The system reconfiguration has failed. Default textclass is used but LyX may not be able to work properly.
