Hi Nathalia,

please read also other post about the same issue, in particular mine, and you'll see that the issue is that DSA installation fails installing .NET Runtime 6.0.9 because current version already installed (by Windows update) is 6.0.10, ie. a more recent version than the one DSA tries to install....

Hi DELL-Nathalia M:

The thread LaurentGrenet is referring to is their 13-Oct-2022 Unable to Update DellSupport Assist to Latest Rev.

I still had .NET Runtime v6.0.9 when the SupportAssist v3.12.3.5 update was offered to my Inspiron 5584 on 11-Oct-2022 (i.e., it was before Windows Update delivered the KB5015391 .NET Runtime v6.0.10  update as part of my Oct 2022 Patch Tuesday updates) so perhaps that's why I had no problem updating from SupportAssist v3.11.4.29 to v3.12.3.5.

Hi Nathalia,

please read also other post about the same issue, in particular mine, and you'll see that the issue is that DSA installation fails installing .NET Runtime 6.0.9 because current version already installed (by Windows update) is 6.0.10, ie. a more recent version than the one DSA tries to install....

Here, and nowhere else, is the problem !

This is probably due to the fact that DSA, when checking .NET runtime installed, compare versions in alphabetic mode, rather han in numeric one, leading it to consider that 6.0.9 is above 6.0.10 (while it's obviously the contrary)...

Hey!

Thank you for clarifying, I will share this information with our engineers.

@LaurentGrenet can you try uninstalling the latest version 6.0.10 and install the previous one 6.0.9?

I know it's not ideal, but it seems to have a conflict between DSA and version 6.0.10.

Sure, I won't do that !

If MSoft publish a new version of .NET runtime, there is surely good reason for that. Most likely, to avoid some security issue.

While I'm convinced there is no conflict between DSA and .Net 6.0.10 : For me, the most likely reason of the issue is that, at install, DSA checks if AT LEAST .Net 6.0.9 is installed. And when it founds that 6.0.10 version is installed, it compares this version number wit 6.0.9, but erroneously makes its comparision alphabetically instead of numerically (and, yes, alphabetically speaking, 6.0.10 is "before" 6.0.9). As a result, DSA considers that .NET has to be "upgraded" to 6.0.9 which is (hopefully !) impossible from .NET perspective.

So, rather than to ask users to do such things, please ask technical engineers to create a new version of DSA installer that, when it checks currently installed version of .NET, is able to understand that if minimum version is 6.0.9, this requirement is already fulfilled if 6.0.10 is already installed.

Or, in case there is really incompatibility of DSA with 6.0.10 (I don't believe it 1 second), fix DSA itself to resolve the conflict... or ask MSoft to publish a 6.0.11 that solve the issue.

But surely, I won't downgrade an "OS layer soft" (ie. .NET runtime) to "please" a "User layer" soft (ie. DSA)

I am really surprised that you even dare to make this request. It is not serious, and is not a sign of seriousness on the part of Dell

PS : I just checked in MSoft Catalog  : .NET 6.0.10 is indeed a security update (KB5019351 and not KB5015391 as mentioned by @lmacri )

Thank you very much Nathalia M for this solution which worked for me because I had received a message from support assist asking me to update it in vain after having tried several times I installed version 6 of net runtime and then I went to this link to reinstall Support Assist. I'm really happy support assist is working again.

Hi, thanks for your support. Unfortunately, those steps didn't work. I get an error message when trying to use de msi installer: "ui mode not supported". It seems that there's a problem with the installer. When trying to install with de SA.exe from Dell, I got this data from the installer log:
INFO...: ProcessName : msiexec.exe is getting executed
INFO...: process return Code : 1603
ERROR...: SupportAssistInstallerPackage - Some Error occured while upgrading msi SupportAssist Agent
ERROR...: SupportAssist download/installation failed with return code: msiinstallationfailed

I don't even had to uninstall a prevoius version of SA, since I am restoring my laptop. I did uninstalled .NET 6.0.10 and then followed your suggestions.

Do you know if there's anything else to try?

Thanks again

instead of uninstalling etc [recommendation from DELL people] if you have a later .NET runtime you should be able to use that (not the archaic v5.0 that DDM may require). My earlier post said

DDM installed OK but at runtime then requires .NET v5.0 runtime, but failed to download that on system that lacks .NET v5.0 although box had the latest .NET v7.0
I found that editing C:\Program Files\Dell\Dell Display Manager 2.0\DDM.runtimeconfig.json happily used my latest version
{
"runtimeOptions": {
"tfm": "net7.0",
"framework": {
"name": "Microsoft.WindowsDesktop.App",
"version": "7.0.0"
}
}
}

Dell should be embarrassed that the "accepted solution" forces the user to uninstall the existing tool and install prerequisites to get it to work.  That's YOUR job.  Provide a freaking installer that actually works!  Anyway, your 1st step doesn't actually work for me -- running the MS Install Uninstall tool doesn't actually find any issues, yet I still can't install SupportAssist.  Should I attempt to install via Add/Remove programs?
