Probably a silly question, but why use 7z here? Is gs.exe actually compressed in the last step and this is expanding it, or is there some Windows convention I'm unaware of where 7z can be used to run exes?

This is an NSIS installer:

❯ gh release download -R ArtifexSoftware/ghostpdl-downloads --pattern "gs*w64.exe" --output gs.exe
❯ file gs.exe
gs.exe: PE32 executable (GUI) Intel 80386, for MS Windows, Nullsoft Installer self-extracting archive

And 7z knows how to extract NSIS, it's listed under "Unpacking only" at https://www.7-zip.org. 7z x only extracts, not installs: https://7-zip.opensource.jp/chm/cmdline/commands/extract_full.htm We don't need to run the installer, just get the files in the right place.

History corner: NSIS was first developed for Winamp :)
