SupportAssist - installation failed message.

fwiw, this did not work for me, in fact nothing does, cannot get new download of client program to run properly which was said to be prerequisite for supportassist. Will wait for new release or just keep on ignoring ... 

Thank you,

this solved 1 month of tests to solve the failure of SupportAssist Re-Installation ("Failure Message").

As DotNet 5.x is officially end of life, I should I have cleaned it up.

Exact same issue. I reached out to Dell Support and they have not been able to resolve. Everything they've told me to do has made matters worse. I'm scared to do anything they tell me now. They have to get their act together, especially since so many are having the same issue(based on what I'm seeing in user forums). They need to step up and figure out why this is happening and how to fix it. I'm very disappointed in Dell Support!

what version of windows (OS) are you using ?

Simply uninstall all .NET versions except 5.0.17.

Hi Dellorianer:

The release notes <here> for the latest SupportAssist v3.12.3.5 (rel. 11-Oct-2022) state that .NET (Core) Runtime v6.x is a new system requirement, so I'm guessing SupportAssist v3.12.3.5 won't run correctly if the unsupported .NET Runtime v.5.0.17 is the only .NET (Core) Runtime installed.  I currently have MS .NET Runtime v6.0.10 installed on my Win 10 Pro v21H2 machine and my SupportAssist v3.12.3.5 seems to be running correctly.

Dell Inspiron 15 5584, Intel i5-8265U CPU, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G NVMe SSD, Intel UHD Graphics 620

Tried all that - didn't work.  Useless No obvious error messages or entries in the log about why its failed.  Just tells you to reboot and try again.  Very poor programming.

Same for me, installed .NET (Core) Runtime v6.x and all the stuff found in .NET 6.0 SDK (v6.0.402) - Windows x64 Installer disabled my Mc Afee Antivirus but still the same message to relaunch the PC when trying to install SupportAssistInstaller...

What the H.E.L.L is going on at Dell???

Hi SGSMikeG / LeMachdu25:

This is an older thread about SupportAssist v3.11.4.29 (rel. 23-Jun-2022) that was marked as "Solved" several months ago. If you are having issues with the current SupportAssist v3.12.3.5 (rel. 11-Oct-2022) and require further assistance your problem might receive more attention if you started your own topic in this Dell SupportAssist for PCs board. Please include the following:

• Dell computer model
• Windows OS [if Win 10 or Win 11, include the edition (Home, Pro, etc.), version and OS build number shown at Settings | System | About | Windows Specifications]
• Antivirus name and version
• BIOS version [open a Run dialog box (Windows key + R) and enter msinfo32 to open your System information panel; look for the field named ""BIOS Date/Version")
• Version numbers of Dell SupportAssist and all Microsoft .NET Runtimes currently shown at Control Panel | Programs | Programs and Features
• If you have Win 10 or Win 11, whether any Windows Core Isolation security features like Memory Integrity (located at Settings | Update & Security | Windows Security | Device Security | Core Isolation on my Win 10 Pro v21H2 laptop) are ENABLED
• If the Windows Fast Startup power option, which can interfere with the loading of services and drivers of third-party software at boot-up and cause unexpected problems, is ENABLED
• Details of any error message you see when you try to install or run SupportAssist and what steps you've taken, if any, to try and solve the problem

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.

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.
