17 R5, Dell SupportAssist x64 v3.11.2.143 Installation failed

My inspiration laptop was able to successfully update supportassist while my Alienware desktop failed to update or install it. Both systems have the same Net Runtime version installed, which is 5.0.17. I don't think that it is a .Net issue, on my end, to say the least. 

I found that even if you were to uninstall this net runtime, the SA installer would reinstall it for you during the installation process.

Sorry, just wanted to make a correction to my previous post.  My SupportAssist updated to v3.11.4.29 today.

Hi crimsom:

Further to my 09-Jun-2022 post <above> I launched SupportAssist v3.10.4 today on my Inspiron 5584 and it successfully updated to SupportAssist v3.11.4.19. I ran manual "Get Drivers & Downloads" and "Scan Hardware" scans from the Home tab and they both ran to completion, although I declined to install the update for my Realtek Memory Card Reader driver that the update check found. Note that the 64-bit .NET (Core) Runtime v5.0.16 was automatically installed on my system by Windows Update during my April 2022 Patch Tuesday updates (I still don't know why since I was using SupportAssist v3.10.4 at the time), so I already had .NET (Core) Runtime v5.0.17 (x64) before SupportAssist updated to v3.11.4.19.

The new release notes for SA v3.4.11 (released 23-Jun-2022) say the minimum system software requirement is "Microsoft .NET Framework 4.7.2 and .NET Core Runtime v5.0.14. NOTE If you do not have Microsoft .NET Framework 4.7.2 and .NET Core Runtime v5.0.14, SupportAssist installs the latest Microsoft .NET Framework on your PC." I posted further details today in DavG94's Dell Support Assist Fails to Install about this new requirement, and I'm still confused why Dell would ever release new SupportAssist v3.11.x installers that require the unsupported (and now insecure) .NET (Core) Runtime v5.0.x that went out of support on 10-May-2022.

I recall you posted on 02-May-2022 in 17 R5, SupportAssist v3.10.4 Blue Screen  that you installed the full .NET SDK (software development kit) for .NET v 5.0.16, which is the complete set of libraries and tools required for developers to build and run .NET applications. It probably doesn't matter now since that SDK included the .NET (Core) Runtime v5.0.16, but for other users following this thread I believe that just installing the Microsoft .NET Runtime v5.0.17 from https://dotnet.microsoft.com/en-us/download/dotnet is sufficient if you only have an application on your computer like SupportAssist that requires .NET (Core) Runtime v5.0.x to run correctly and you aren't actually developing .NET applications.

Regardless, I would agree that the current problem you're having with the SupportAssist v3.11.x installers on your Alienware 17 R5 likely has nothing to do with a missing .NET (Core) Runtime v5.0.x.

Thank you @crimsom for clarifying the .Net runtime subject.

You mentioned Dell installation code was at fault, as well as providing an example, which I'm assuming was pulled from an installation log of sorts. Where is the location of that log?

I've noticed in that one of your screenshots sent in this thread was about your reliability monitor and the SA installer error. You mentioned that it would give warnings every time the installation failed. Looking closely at the warning message, there is an error return code, numbered 1603, which is the same error code a user on this thread and I got. That user, @AnnCast, also has an Alienware machine - as mentioned in his post regarding their installer logs. 

This error code can be found in the installer logs at C:\ProgramData\Dell\SupportAssist\Agent\logs\installer\installer.txt as well as the reliability monitor. 

Do you get similar errors or completely different ones? Just making sure I'm not totally alone in this problem. 

Hi @Admiral1989  thank you for your enquiry.

I can only comment on my Alienware 17 R5 diagnostic journey. I do not work for Dell and consequently do not know how other systems behave. In summary, Error code 1603 = Fatal error during installation (of SupportAssist). The root cause of Blue Screen was fixed by getting windows to install more recent file. The SupportAssist temporary installation file was not valid because the msi file name was different to what it should be (Dell to get a new code writer). Eventually, SupportAssist was listed in Programs and Features, but still not fully installed. Repair was possible to get full installation, so that other Dell applications can use it. I have access to diagnostic tools that other users may not have or have difficulty in interpreting Microsoft error codes encountered during their system's diagnostic journey. 

Dell Quality Assurance on these recent SupportAssist version updates is poor. 

I have the same error code in readability as you on both my xps 15 and AW17R3. 

I dont want to mess with the system when this clearly is a problem dell have to fix.

I tried to download and run the installation file from dell (https://www.dell.com/support/contents/en-us/article/product-support/self-support-knowledgebase/software-and-downloads/supportassist) but the same error message during the update appears. Will try one last attempt, but if that fails I will wait for a automatic fix from dell and/or Microsoft. 

Hi crimsom:

Just another FYI that employee DELL-Nathalia M posted today (28-Jun-2022) in Admiral1989's  SupportAssist - Installation Failed Message that Dell is currently working on a fix for some of the recent SupportAssist installation errors.

Moderator jbilinski also posted in Admiral1989's thread today that "Dell TechHub replaces Dell Hardware Scan service and is needed to run the Hardware Scan panel" so that's another major change that's been introduced in SupportAssist v3.11.4.29, in addition to the new system requirement for the unsupported (and now insecure) .NET (Core) Runtime v5.0.x that was discussed in DavG94's Dell SupportAssist Fails to Install.

Hi All,

Is there any news from Dell on this yet?

I maintain 3 Dell PCs (XPS 8900, XPS 8930 & Inspiron 17 5767, all running Windows 10) and none of them have been able to update SupportAssist for the last 4 months.  Windows Update repeatedly reports "Unsuccessful application installation", and although when I open SupportAssist it produces a prompt offering to update itself, that fails too.  I am currently on SupportAssist 3.11.2.143.

I would have thought Dell must be aware that they are pushing out updates which are not installing...

I had the same installation error with Support Assist. The issue with mine seemed to be that the Dell Client Management Service was somehow Disabled. Trying all of these other solutions didn't work for me. But, as soon as I enabled the Dell Client Management Service, the Support Assist App was able to be installed. And, suddenly worked correctly.

I too found that the Dell Client Management Service had mysteriously become Disabled on all three PCs which I maintain, and so I enabled it and set the Startup Type to Automatic (Delayed Start, Trigger Start).  In my case this enabled Dell Update to run correctly, but had no immediate effect on the repeated failure of SupportAssist to update.

However, 3 days ago on 27th August SupportAssist was successfully updated automatically by Windows Update (to version 3.12.1.180), so Dell finally seems to have cracked the problem!
