I thought I could solve my trouble installing Lyx 1.4.4, after unistalling the
1.4.1 and tex components .
I chose the windows web installer, but while running the setup it tried to connect both
to Miktex and ImageMagick sites for downloading...and it returned an error like
"failed downloading MikTex/ImageMagick..."
Do you have any clue?
The installer should take you through a series of screens relating to
necessary external programs (MikTeX, ImageMagick, Ghostscript). Each
time it should give you the option of using an installed version (if you
have the program installed, and if the LyX installer can find it),
downloading from the Internet, or just bypassing it. If the installer
sees a version of the program on your system, it will default to the
"use the existing version" option.
So if you have MikTeX and ImageMagick installed, and the LyX installer
is defaulting to the download option, you just need to select the other
option and point it to where those packages sit on your machine. If you
are missing them (for instance, if by uninstalling the "tex components"
you mean you uninstalled MikTeX), then you need either to download and
install them before installing LyX, for to let LyX take you to the
download sites (which of course requires a live Internet connection).
I've not used the download option myself. My impression was that, at
least in earlier versions, it would open the download page from the
remote server but not do the download automatically (i.e., you would
have to click around the web page to initiate the download). I suspect
(but am not sure) that you would also have to install the downloaded
packages yourself before letting LyX continue with installation.
Alternatively, if you are missing all three packages, you could switch
to the "alternative" LyX installer (74 MB download) on the Wiki, which
bundles everything you need.
