So, we have still having issues with installing DCU & DSA. One day I was chatting with ChatGPT and I now have a PowerShell command that installs DCU and it has worked all but one time.

here is the command, run PowerShell as admin

winget install --id Dell.CommandUpdate -e --source winget

First this will install dotNET 8.0 then install DCU

Hi,

We have same issue with computer, Microsoft Win. Desktop Runtime 8.0.26 (x64) already installed, and try to uninstall & reinstall DCU but DCU start and stopped after few minutes.

@Rich Downey​ this worked smoothly for me, the only issue is that it downloaded ver 5.7.0 while 5.7.1 is available. Will have to wait a while I suppose :)

Something has definitely changed with the installation of Dell Update Command.   I've tried to install version 5.5 on 3 new freshly installed Windows 11 computers, and each time I get the "The wizard was interupted before Dell Command|Update could be completely installed" error.

I have to perform the updates thru the Dell support website now.

@Excalibur1701​ At first I thought it was the TPM update, but that only showed up once, then I was installing all the updates using Dell SupportAssist via the web site. NOW! I start the install for DCU, I want 1.5 to 2 minutes, then I go into Task Manager and KILL the installer process. and DCU works fine. 

Yes, dell broke DCU and I hope they do a fix, OR! if an update to TPM or some other driver is required, they should issue a statement. 

Hi!

Today I have encountered this issue while I was preparing a Dell Precision workstation at work. Finally, making some searches and tests on the computer I have found out that Dell Command Update 5.5 requires ".Net Desktop Runtime 8" to be installed previously on the system.

You can download the installer from the following URL:

Download .NET 8.0 (Linux, macOS, and Windows)

(Maybe installing just ".NET Runtime 8" instead of ".Net Desktop Runtime 8" is enough, I haven´t tested it yet.)

I hope it helps more people with the same trouble.

Regards!

Have been having the same issue on new Dell systems that are being re-imaged prior to deployement.

Taking Amuro_Ray's suggestion was successful.

Install failed, added .NET Runtime (not Desktop version) 8.0 and then immediately began the installation again, and that was successful.

Thanks for the tip!

@Amuro_Ray.​ Tried this ONCE and it worked, tried it again  and failed 

Getting kind of tired of this! 

This is not resolved, sadly still receiving the error.

@Rich Downey 
Ran Dell SupportAssist (DSA), updates did not include the TPM but after the restart the Dell Update Command successfully installed.

Very odd.
