I manage approx. 200 Dell devices throughout a medium size organisation across multiple geographic sites and remote users.
We deploy Dell Command | Update (Windows Platform Version) to keep the machines up to date.
Since approx. v 4.2.0 and above (we're now deploying 4.3.0 which appears to have the same issue), on all our devices; whenever the product updates, it no longer functions. CLI shows "an unexpected fatal error occurred", the GUI just refuses to start following the splash screen.
A Windows event log trawl hints that the software is failing due to a .NET unhandled exception:
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.NullReferenceException
The only way I have discovered to resolve the issue is a manual uninstall and reinstall of the product, which is clearly not an acceptable in an enterprise environment.
Anyone encountered this issue or a workaround / resolve prior to us complaining to our account manager? At present, software written by Fisher Price would be more reliable.
When the unhandled exception issue occurs, the only way to resolve it seems to be:
1. Manually remove DCU using control panel
2. Restart the machine
3. Reinstall DCU 4.4.0
The product will then run normally.
Thank you! We have received the required details. We will work towards a resolution. In the meantime, you may also receive assistance or suggestions from the community members.

We're running through similar issue with our small org. All our devices are XPS and have a range of different Dell update utilities (Dell Command | Update, Dell Update, Dell Universal Update). We are trying to standardized using Dell Command Update however it requires uninstalling any other version of Dell update utilities which we are trying to achieve through Intune. Issue is that our detection rule is looking for the DellUpdate.exe or DCU.exe which can't be found on many of our devices. Where are the Dell Update and DCU application executables located? Obviously we can go around to each device and uninstall through Apps and Features but we'd like this automated.
I've been struggling with DCU v4.5.0 crashing/hanging, too. DCU-CLI can't run any commands and crashes after 3 minutes with "fatal error" while the GUI displays the splash screen and eventually disappears. Uninstalling & reinstalling works for a bit, but inevitably I end up in this same spot. This post clued me in that there's a "Dell Client Management Service" that sure enough, doesn't start, so this is the core culprit. Knowing that an uninstall/reinstall fixes it, I set out to reverse engineer this the best I could & came up with the following workaround.
When I delete the "C:\ProgramData\Dell\UpdateService" folder in its entirety, the service is able to start & re-populate with fresh files.
I went further with this trying to delete temp files, review the UpdateScheduler.dat file contents, etc, but never could get to a more granular fix other that nuking the entire folder & letting it repopulate.
Hope this helps you at least not have to uninstall/reinstall. Thank goodness it can be automated, too. If you or anyone else gains any further insight, please share! TY! --Matt
