How to update / upgrade NSIS

[Simon-Laux]

We have an issue where the installer is crashing sometimes (when the user directory contains spaces) before doing anything.
deltachat/deltachat-desktop#1269

I tried understanding the scripts but I currently don't have the time to find out how exactly everything works.

Can you describe what I need to do to make a build for or provide builds for:

• the current nsis release (3.0.6.1 at the time of writing)
• the current nsis master/nightly/next-release (3.0.7 at the time of writing)

I want to test if these new versions of NSIS can fix the issue.

I tried to figure this one out as well but didn't manage to get far on Windows. There are these scripts that have hints as to what needs to be done

I could use an updated one for my PR adding debug logging to nsis installers electron-userland/electron-builder#6024
