* Add option to bundle required ImageMagick/Ghostscript files without the need to modify registry keys that belong to the original applications. This allows for full support for installation by limited users, gives different users the possibility to have a different setup of all LyX tools and reduces download size. The necessary files will be included in the dependency package.
* Python, ImageMagick and Ghostscript will now all be compiled using the same MSVC compiler and can use the same C runtimes. This reduces the installer size.
* Compile Python files during installation to improve performance. Limited users may not have access to the installation folders so the files cannot be compiled afterwards.
* Only the settings that typically need to be changed for LyX releases are now in settings.nsh.
* Rename launcher executable to LyXLauncher.exe to match the alternative installer.
* Minor fixes and cleanup.

* use nsDialogs instead of InstallOptions for custom wizard pages, faster & easier to customize
* upgrade to Modern UI 2
* use MultiUser.nsh to support multiple installation modes (all users / current user) in a much more simple way
* use LangFile.nsh for the language files, again less scripting required
* simplified installer structure
