Hi,I would like to point out that some of the Lyx pages are indicating compatibility to Windows XP or even Windows 2000, which is no longer the case:
German Download https://www.lyx.org/WebDe.Download Lyx Wiki, Windows http://wiki.lyx.org/Windows/Windows etc. The latest version for XP is 2.1.5, no idea about Server 2003 or 2000. Regards, Armin
