Description This is the readme of the variant "update" of the LyXWinInstaller. Please read this file carefully to prevent troubles with the installer. The LyXWinInstaller installs the wordprocessor "LyX" (www.lyx.org) and some needed programs on Windows 2000/XP/XPx64/Vista/7. ! Win95, Win98, and WinME are NOT supported. ! --- General The installer variant "update" is designed to update existing an LyX installation. It therefore only actualized some registry entries and updates the file that were modified since the last LyX release. Custom user settings and third party programs like ImageMagick are not touched. --- Prerequisites You must have the last LyX-version installed, otherwise the update installer quits with a varning about the wrong LyX version. Note: The last LyX-version should have been installed using also LyXWinInstaller to assure that the update works as expected. --- License The scripts of the LyXWinInstaller are released under the GNU General Public License (GPL). A package with the sourcecode can be found in the section "LyxWinInstallerSource" of http://developer.berlios.de/project/showfiles.php?group_id=5117 The license files of all used programs can be found in the subdirectory "bin" of LyX's installation folder.
