Give NSIS a try

[lazka]

NSIS would give us

• Greater flexibility during the installation process
• Smaller installer size (no Qt)
• Maybe silent CLI installation

We use innosetup to ship R and rtools (which is a modified version of msys2): https://cran.r-project.org/bin/windows/Rtools/

The script to create the installer is here: https://github.com/r-windows/rtools-installer

Thanks. The upside of nsis is that we have it in the repo and it can be build from source, so I'd still like to try that first. If it turns out to be not working your scripts will come in handy :)

I'm also building a similar thing for installing Cmdstan on Windows through an executable file. If you have something running let me know I would love to take that approach to installing Cmdstan.
