Thanks again for your advice. I am having a few issues with installation:
In step 4 of the installation instructions ("In the "Select Packages" view...") I did not initially see lyx and related packages. After clicking "View" a few times until "Not Installed" was displayed, the relevant packages were displayed (lyx, lyxdict, etc, although not LyXwin as stated in step 4). When installing, I then got popup messages from Cygwin setup "Can't open (null) for reading: No such file" while setup was installing cygspawn-1.0.0-2-src, dtltools-0.6.2-src, dvipost-1.1-4-src, latex2rtf-1.9.17-2.src, lyxsupport-2.0-src. Finally, lyx still finds my windows installation rather than the new cygwin version: $ lyx -version LyX 2.0.8 (2014-04-14) Built on Apr 15 2014, 23:03:32 CMake Build I'm assuming I need to edit the cygwin PATH variable, since this still includes /cygdrive/c/Program Files (x86)/LyX 2.0/bin however, I can't find the right directory in cygwin, i.e. /usr/local/share/lyx/ does not exist, nor can I find lyx.exe, lyxwin.exe, or any lyx directory in my cygwin installation. I'm not sure that I've looked everywhere, but I have looked everywhere I can think of, including C:\cygwin64\bin C:\cygwin64\etc C:\cygwin64\lib C:\cygwin64\usr C:\cygwin64\usr\local C:\cygwin64\usr\share which leads me to suspect my installation was not successful after all. Any suggestions?
