Remove old Windows Installer
Hi,

Does anyone know how I can make my NSIS installer remove the old version of the application that was put there by the Windows Installer?

Any/all assistance greatly appreciated!

Cheers!
Dean

See this example:
${NSISDIR}\Example\makensis.nsi
It will check the installed version and show a custom page that allow you update or remove.

If you mean you want to uninstall an application installed by the MS Windows installer (MSI package), you can use the /x switch:
