Does anyone have a silent installer for a Dell BIOS update? Or how can I setup BIOS update installer on Lansweeper?

Just FYI, for 64bit BIOS updates, you need the Dell Flash Utility.

So I setup a CMD
\\nas\install\dell-bios\Flash64W.exe /b=\\nas\install\dell-bios\OptiPlex_3050_1.7.9.exe /f /s /p=Password /l=C:\dell-bios-update-1.7.9.txt

/b is the location of the flash file
/s is silent
/f is force restart
/l makes log file.

The Flash64W.exe is a Dell specific flash utility. Running this first with 64bit machines is required (as I found out the hard way of wasting bunch of time on this for nothing)

I read up more bout it here:

Dell Flasher Utility is here:

Hope this helps others out.

silent install:

biosupdate.exe /s


but I like to run all driver updates from the dell command update, install is this:

msiexec.exe /i "{PackageShare}\Installers\dell\dellcommand\dcu_setup_2_3_1\DellCommandUpdate.msi" /norestart /qn


and then run the script to run all driver updates from it:

"C:\Program Files (x86)\Dell\CommandUpdate\dcu-cli.exe" /log C:\Dell\Temp\logs


run this command before the above script if you have bitlocker, suspends bitlocker and will allow for the bios to be updated for 1 reboot:

powershell.exe -executionpolicy bypass -command "Suspend-BitLocker -MountPoint C: -RebootCount 1"
