We are currently using NSIS 2.X. One problem is that it cannot be built for Windows x64. This has been solved with the 3.0 version, which is currently in beta. We should eventually upgrade.
NSIS 3.0 Beta 3 has been released: http://nsis.sourceforge.net/Docs/AppendixF.html#v3.0b3 My guess is that it is good enough for us.
NSIS 3.0 was released July 25, 2016. NSIS 3.01 was released December 11, 2016.

Right now we have a universal installer for Windows that automatically selects 32-bit or 64-bit ThinLinc client. That means the installer needs to be 32-bit in order to work everywhere. This will be interesting in a future when we've dropped 32-bit support.
It seems the latest NSIS does support 64-bit since I can see that Fedora does such builds.
