--- Comment #5 from João Paulo <joaopauloag-freedesktop at yahoo.com.br> ---
Wow, thanks for the info! I didn't know all that. And I agree it's not good to
provide .zip files with split installers nor providing different packages for
different scenarios (it not only creates extra complexity, but also duplicates
the storage space needed to provide each new LibreOffice version).

Anyway, I found a workaround: First make an administrative install folder (the
"/A" option passed to msiexec.exe extracts everything to a folder, including
the **stripped down** .msi file) and then use the administrative install folder
to install LibreOffice.

Unfortunately, the workaround creates some undesired side effects
:
(a) The digital signatures for the .msi file are invalidated (not a problem to
my configured machines and users, but can be for someone else);
(b) More storage space (on the server or on the client machine) is needed to
deploy LibreOffice. It can be a problem, as the administrative install folder
for LibreOffice 6.1.4.2 x64 alone is 1.172.491.255 bytes, against 283.185.152
bytes of the .msi which has a compressed .cab file, and not all installs can be
made through a fast network or any network at all (slow network means it's
better to use the compressed .msi file with embedded .cab file or even a
physical media as a pen-drive or portable HDD);
(c) If there is not enough storage on the server or the setup media or fast
enough network connection to serve the administrative install folder, then it
will be needed more time to complete setup (not a problem if using a portable
HDD as it appears only when installing, which is not frequent -- but is a
problem through a slow network connection).

But then the completed setup uses less space (as the cached .msi file inside
\Windows\Installer folder is the stripped down without the internal .cab file).
The cached .msi file is now just 20.336.640 bytes (or 11.943.936 bytes if NTFS
compression on that folder is enabled), vs. the original size of 283.185.152
bytes (or 274.460.672 bytes if NTFS compression is enabled) after installing
LibreOffice 6.1.4.2 x64.

I adapted my previous install script (I use a .cmd file on every deployment) to
use this new logic and I'll copy (a stripped down version of) it here (I don't
know a better place to publish a workaround):
