What do I need to install and/or do to use LyX for Beamer documents on Windows 7?
I've installed LyX and MiKTeX, but when I try to create a new Beamer document, I get an error.
LyX does not install the Beamer document class by default on Windows7. Use the MiKTeX package manager to install the necessary packages. Then, open LyX and hit Tools>Reconfigure. The Beamer document will work now.
