haim.ros...@gmail.com: How about this: This version of LyX needs MikTeX v. ? at least. The installer found only earlier version of MikTeX / The installer could not find any installation of MikTeX on your system. And the buttons shall read 'Cancel' and 'Update MikTeX and install LyX' or 'Install MikTeX & LyX". Perhaps it should be clear somehow that the installer updates MikTeX to the most recent version, and tell the user what is the path of the old MikTeX detected by installer.
PS Is there an option to have two different MikTeX versions installed on the same system? If there is such an option, then we need an option to tell that's path to this installer. Haim I mean, it should be clear that you cannot continue with old miktex, and it should offer you the update. For the avarage user that is enough. On the other hand, users that do not want to update their old miktex are considered intelligent enough to get the point that this installation would ruin their miktex habits. And if they want to get another supported miktex version, e.g. the first supported version, they can figure out they can do it on their own. Haim
