Had this issue with deployment with Dell command update. I use PDQ Deploy. After much online reading found that a bach file is easyer to work with.
my code looks like this
cd C:\Program Files\Dell\CommandUpdate
dcu-cli /version
dcu-cli /scan
dcu-cli /applyUpdates -encryptedPasswordFile="???" -encryptionKey="???"
Also not sure if you are trying to run the scan and the apply in the same code. I found that it is more stable to run them in diffrent steps.
hope this helps

I think I fixed the issue by changing “If ($DCUVersionInstalled -ne $false){[Version]$CurrentVersion = $DCUVersionInstalled.Version}” to “If ($DCUVersionInstalled -ne $false){[Version]$CurrentVersion = [Version]$DCUVersionInstalled}” Now the function does not attempt to install DCU since the currently installed version if greater than the script detected available version from Dell. The CurrentVersion variable was now set to version value 5.4.0 after the fix. I was running the functions inside of PowerShell ISE if that makes any difference.

r/PowerShell on Reddit: dell command update
March 14, 2024 -
Good evening everyone.
So, I created a powershell script to update a number of pc's (same model-dell). The issue is that when the script runs dell command update, a black cmd screen pops up on the user's display. Is there a way to prevent this popup from appearing?
This is the code I'm using atm:
# Dell Command Update
# Define paths and options for Dell Command Update
$dellCommandUpdatePath = "C:\Program Files\Dell\CommandUpdate\dcu-cli.exe"
$logFolderPathDCU = "C:\Logs\DellCommandUpdate"

Is that the full script? Where is the command when you actually run it?

Run it under a different user context. Or try adding -WindowStyle Hidden or -NoNewWindow at the end of the executable/ start-process call. I imagine somewhere in your script you have a line executing the command with some switches?
