somewhere between Version 1.30 and 1.33 of the windows client the installer changed to use a per-user installation as a default when performing a silent install. For the love of god i couldn´t find any flag/option to create a machine-wide installation again.
Also i noticed, that the installer always downloads content from the internet. Is there any way to obtain an offline installer?
I’ve just spent three hours looking for this information myself. It’s not easy to figure out. I’m hoping someone at Bitwarden could make an actual help article for admins that lists the installer parameters and the additional info on offline/standalone installation. Here are the steps that I’ve found:
Disclaimer: These steps worked for me in my test environment but your mileage may vary
Parameters:
/S (case sensitive) Runs the installer silently with no graphical interface
/allusers (unsure of case sensitivity) Runs the installer for all users - requires UAC / admin creds
Standalone/Offline:
Extract the .nsis file from the .nsis.7z file and then place a copy of the .nsis file in the same location as the installer executable before running the installer. Note that versions must match.
