Dear Misters, I wold begin my request with a special "thanks" to all of you for the continuing efforts in order to
make LyX even more user friendly, as my favourite LaTeX front-end. Recently, I came up with a problem with the new release of the stabilized version 2.0.5, I installed LyX 2.0.4 and MikTeX on 9-10-12, since the version 2.0.5 has some useful improvements, I thought that it could be easy to update using a simple "installer" as the comment on the site states: Installer: LyX-2.0.5.-Installer-2.exe (~35 MB) Download this one if you already have an older version of LyX installed and you want to update it. This installer requires that LaTeX (MikTeX or TeXLive) already be installed. With Windows 7 I wonder if the direct installation of the *.exe file implies the formation of two distinct versions of LyX at the same time or, as the comment says, the update of my current version. I hope you will be able to give me the detailed explanation on how the version update should be done properly. Best Regards Andrea Landella P.S.:I truly apologize for any possible grammatical mistakes, because English is not my first language.
