Precision 5540 - SupportAssist - Unexpected error occurred

All of a sudden Dell SupportAssist stopped working. It giving Unexpected error during driver scan. Looks both my personal and office laptops are showing the same error.

OS : Windows 11 Pro

SupportAssist Version : 3.14

Tried all these

  1. Reinstalled app - no help
  2. .NET frameworks installed
  3. Removed C:\ProgramData\Dell respective folders for SupportAssist after uninstall.
  4. Both SupportAssist services are running fine.

Log - C:\ProgramData\Dell\SupportAssist\Agent\logs\Application\SupportAssistAgent.log show the below error. It looks weird, looks like Dell client issue. Who can help here ?

"Type": "SAConsumer",
  "Exception": {
    "Message": "Scan failed!",
    "Recovery": false,
    "Type": "Dell.SupportAssist.Client.Plugin.Esupport.Helper.ResponseMethods+ScanFailureException"
  "OSName": null,
  "OSVersion": null

Here is the solution to the issue, found this when I installed another software, and SupportAssist / Command Update started working. 

Install these, and you should be good to go.

I have the same problem with an XPS 8930 and an XPS 8940. Additionally if I attempt to run the Dell Update app, I receive an error message of "Unable to Retrieve System Inventory Information."  Event viewer shows "Faulting application name: invcol.exe, version:, time stamp: 0x64d348a4."

Same problem on XPS 8950 this morning. Required services running. No issues on 22-Aug. Uninstalled, restarted, reinstalled, waited. Same error. Installed Windows update KB4023057 on 25-Aug. Cannot uninstall to verify.

Same problem with my XPS 8950 with Windows 11. I recall there was an update to Dell Update about a week ago.

I am having the same problem(s) on my Alienware R15 - both SupportAssist (unexpected error occured) and Alienware Update (unable to retrieve system inventory information) stopped working last week (~ 8/24/23).

I've tried deleting and reinstalling SupportAssist (using the Microsoft Troubleshooter full uninstall) to no avail).

For me the resolution to this problem, which I dealt with just this morning, was a BIOS update. A manual check for a BIOS update on Dell Support's Drivers & Downloads page revealed that the current BIOS, version 1.14, which was released just earlier this month, was different from the version 1.13 that I was actually running. A BIOS update followed by an uninstall/reboot/reinstall of both the Dell Update application and Support Assist fixed everything.

Good luck

What worked for me? Reinstalled BIOS 1.14.

P.S. Device manager still reports BIOS version 1.13, but UEFI shows 1.14.

Jack K & Not Two,

That worked for me! SupportAssist (or the AW Update app) had updated my BIOS to 1.15 last week or so, and that’s when I started having the problems.

I manually updated the BIOS just now and the problem has gone away. Thank you!

@Not Two and @Jack K. and @adamcb_089aca 

Thank you for your posts. I was running into issues with Dell SupportAssist on a Dell Inspiron 3670 tower with Windows 11 (had upgraded from Windows 10 a couple years ago) getting stuck / stalling out on various parts of the scans and occasionally the dreaded "unexpected error". I keep all my drivers, BIOS, applications, and OS diligently updated, so I never suspected that it could be a BIOS issue. After several uninstall / reinstall attempts didn't help, I found this thread. Even though my BIOS was absolutely current, simply re-installing the BIOS update for the same exact / current version seems to have resolved the issues.
