LO w/o admin; download the installer, and use msiexec to run it from the command line (regular CMD prompt):
msiexec /a LibreOffice_7.5.4_Win_x86-64.msi
Choose your folder, then let it install. Then download and install the help pack in exactly the same way.
msiexec /a LibreOffice_7.5.4_Win_x86-64_helppack_en-US.msi
I chose to use:
C:\Users\darren\installs\LO
So the executable files are in
C:\Users\darren\installs\LO\program
So I added this to my Windows path. That allows me to run it from the command line, which is handy for LibreOffice.
