I'm the author of

• NsisDDE plug-in
• NsisXML plug-in
• NsisFirewall plug-in

I also have extensive knowledge around creating full-featured professional installers using NSIS. This includes :

• Offer the user to uninstall the previous installation of the application before continuing
• Exiting running instance of application before (un)installation
• Switching gracefully to administrator rights (eventually asking user for credentials) before continuing installation (under 2000,XP,Vista)
• Deal gracefully with Vista UAC and large installers that usually slows down Windows Vista
• Running the program under logged user account (not administrator) at the end of installation
• Installing MS Visual CRT libraries (through MSI/MSM)
• Have a semi-automatic installation display on some command line switch (only show a progress bar in this case)
• Register application with Windows Firewall
• Running console process hidden during installation
• Check for Windows versions compatibility before installation
• Automatic generation of a NSH header by extracting Version Information from EXE files, useful for generating "Add/Remove program" and Installer Version information
• Tweaking the MUI finish page, or some custom page to download more stuff over Internet during installation

and much more NSIS installers tweaking to make them more user-friendly...
