As discussed with Vincent I added 3 new features:
* LyX can now also be installed over an existing installation of the same LyX version if the users really wants this.
(A message box appears recommending not to do so for test releases and when there are problems with an existing installation of the same release.)
* LyX can now also be installed if the uninstaller executable of a former LyX was accidentally deleted.
(That this case was not handled was more a bug. Thanks Vicent for the pointer.)
* If a user set MiKTeX's automatic package installation to "No" the installer will.
(As discussed with Vincent, if a user has disabled this MiKTeX feature he most probably know the consequences. So respect his decision.)
respect that and not re-enable it.
I would be happy if anybody can spend a translation of the changed installer message.
- known problem: if LyX 2.0.x is installed and you install 2.1rc1, the .lyx file associations will not be updated but if LyX 2.1 is installed on a new PC the file associations work (work is in progress)
- it turned out that the hack to install a stripped-down Perl directly to MiKTEX is not only error-prone, requires admin permission but that it is also not safe because MiKTeX changes the folder structure from time to time. With the new solution Perl is installed directly for LyX like we do for ImageMagick, Python etc.
- for pdfcrop support there is a bug in pdfcriop that the requirement is hardcoded to Ghostscript 32bit - I contacted the pdfcrop author to fix this
- the installer does nw the job of replacing the magyar.ldf with the fixed version [http://wiki.lyx.org/Windows/Hungarian]
- install the Mongolian hyphenation pattern to MiKTeX
- update eLyXer
- update to new MiKTeX installer that fixes a bug with updating Packages
- don't ship cbgreek because it is so huge that its download would last 10 minutes or more
- the installer will now recognize an already installed 64bit MiKTeX
- the installer will still install 32bit MiKTeX for new installations because biblatex does not yet work with 64bit MiKTeX
LaTeX.nsh:
- fix a MiKTeX configuration Problem on 64bit Windows issue discovered in #8417
- don't overwrite MiKTeX's package repository the user might have set purposely
- remove some unused code and simplify some code
- update to JabRef 2.9.2
- LaTeX.nsh: fix bug that installer stopped working if LyX was installed the first time on a computer
- init.nsh:
- fix failing installation of Slovakian spellcheck dictionary
- expand list of available dictionaries as requested by users
- dictionaries.nsh: prevent case that the installer could run an infinite loop if the installation of dictionaries was interrupted
- settings.nsh: use a HTTP repository for MiKTeX instead of FTP because many companies deny FTP access by default in their firewalls
This is already done by the program pdfview every time it is called. This additionally fixes the bug that viewing PDF files could fail if Acrobat was not the default PDF viewer of the system while LyX was installed, but became later the default PDF viewer.
- to be able to support Adobe Reader/Acrobat XI I had to use new binaries for opening/closing PDFs. That way I found the solution for a long standing and super annoying PDF viewing bug (not 100% perfect but works for more than 95% of the cases, while formerly the view failed for all cases where LaTeX run more than once when updating a PDF view)
- avoid doubled semicolon in LaTeX editor path list
- correct path to the JabRef installation folder in LyX's PATH
- updated to JabRef 2.8.1
- rename the installer executables from LyX-205-x-Bundle.exe
- fix uninstallation of Metafile2EPS pinter
- fix un/installation of JabRef if the bundle version is executed without admin privileges
- some whitespace fixes
- detection.nsh:
- fixed detection of the LaTeX source file editors
- removed support for obsolete LaTeX source file editors
- init.nsh:
- don't allow to install an older LyX version over a newer one
- support dictionaries for new languages that will be supported by LyX 2.1
- remove registry entries of current LyX version when installing a newer version over it
