Document windows installers available flags

[jaysonsantos]

Description

I'd like to know what are the possible command-line flags for the installer, I am trying to update an installation recipe for brave on scoop, and the zipped files are not signed so I wanted to use the installers but I cannot find what kind of installer it is and its flags.

Steps to Reproduce

installer.exe /?
installer.exe /help
won't print anything

Actual result:

nothing on the command line, the installer keeps going

Expected result:

information about the install flags

Brave version (brave://version info)

Brave | 1.22.70 Chromium: 89.0.4389.105 (Official Build) (64-bit)
Revision | 14f44e21a9d539cd49c72468a29bfca4fa43f710-refs/branch-heads/4389_90@{#7}
OS | Windows 10 OS Version 2009 (Build 19042.870)

Version/Channel Information:

• Can you reproduce this issue with the current release? yes
• Can you reproduce this issue with the beta channel? yes
• Can you reproduce this issue with the nightly channel? yes

Miscellaneous Information:

If you just point out what installer framework you are using it should also be ok.
Thanks in advance

cc: @mihaiplesa Any help with this one?

[mihaiplesa]

@mherrmann is looking into a few related things but there's some info on:
#6240
#9418

I'll create wiki page to capture.

[mherrmann]

A good default assumption is that Brave installers on Windows support the same command line arguments as Chrome's.

[mihaiplesa]

Trying to find their docs for that but nothing so far.

[Brave-Matt]

@mherrmann is correct. Further, we've listed them on our Help Center for reference.

[mihaiplesa]

@Brave-Matt those ar run-time, not sure we have for install time (options for the installer).

Partly present at https://github.com/google/omaha/blob/master/doc/UsingOmaha.md

[mherrmann]

Brave's installers on Windows are Tagged Meta Installers. Their command-line parsing logic is implemented here. This essentially says that if you pass /silent /install to Brave's tagged meta installer, then it internally invokes BraveUpdate.exe /silent /install "appguid={Brave's UUID}&...". The flags /silent etc. are listed in const_cmd_line.h.

@jaysonsantos does the above answer your questions? If yes, then we'd go ahead and close this issue.

Hey there @mherrmann sute thing, this can be closed

[mherrmann]

Thank you for letting me know @jaysonsantos !

@mherrmann anything we should add to https://github.com/brave/brave-browser/wiki/Brave-omaha?

[mherrmann]

@bsclifton @mihaiplesa and I considered the same question. There's nothing that can be added easily. It would require going through Omaha's C++ code, seeing what flags might be there, reading the code to find out what they do and potentially trying it. We decided to leave it at that if @jaysonsantos' questions were answered.
