This is an update to the post http://www.pokorra.de/2014/12/packaging-nsis-nullsoft-installer-for-centos-rpm/
NSIS (Nullsoft Scriptable Install System) “is a professional open source system to create Windows installers.”
NSIS 3.0 has been released on 25th July 2016: http://nsis.sourceforge.net/News
I have now packages for CentOS7 and Fedora 24: https://lbs.solidcharity.com/package/tpokorra/nsis/nsis. You can find instructions on that page how to install the rpms.
The sources for the package are available here: https://github.com/tpokorra/lbs-nsis/tree/master/nsis
I am using this for example to build nightly installers for OpenPetra standalone for Windows, and the build happens on CentOS7: https://lbs.solidcharity.com/package/tpokorra/openpetra/openpetranow-standalone-nightly. The sources for the installer can be found here: standalone.nsi
