Windows unattended installer

[Charlotte Godley]

Hi,

Forgive me if this is the wrong mailing list, but I’m trying to figure out how 
and if it’s possible to run the windows installer from command line unattended 
without having to click through the GUI. I use lilypond in a python package - 
http://github.com/godley/museparse <http://github.com/godley/museparse> and I’m 
now trying to use appveyor continuous integration so that I know my tests work 
on windows, but to achieve that I need to be able to give it a yml file with 
the instructions on downloading and installing lilypond unattended, and I 
couldn’t find anything on it other than the general universal builder which I 
gather is for creating lilypond installers, not running them. Do you have any 
hints, tips or links to instructions on this?

Thanks,
Charlotte
