SupportAssist installer not running

Hi greatdragao:

What is your Dell computer model, Windows operating system [open a Run dialog box (Windows key + R) and enter winver to find the version and OS build number] and BIOS version?  To find your current BIOS version open a Run dialog box, enter msinfo32 to open your System Information, and look for the field named "BIOS Version / Date" in the summary.

What version of SupportAssist, if any, is shown at Control Panel | Programs | Programs and Features, and has your Dell service warranty expired yet?

Download a fresh copy of the latest SupportAssistInstaller.exe installer from https://downloads.dell.com/serviceability/catalog/SupportAssistInstaller.exe and save it to your Windows desktop, close your browser, right-click that .EXE file, and choose "Run as Administrator". If the installer fails to run to completion again let us know if it displays any warning or error message.

If the SupportAssist installer doesn’t run after clicking "Yes," try running as admin, disabling antivirus, or using Dell’s SupportAssist removal tool first.

Hi RasmiKandhil:

What SupportAssist v4.x removal tool are you referring to? I know that remnants of older SupportAssist installations can sometimes be removed with Microsoft's Program Install and Uninstall Troubleshooter (see my 05-Jan-2025 post in WjSturgis'Support Assist will not run about how to perform a clean reinstall of SupportAssist) but I don't know of any removal tool offered by Dell that will remove orphaned files and registry entries left behind after a "normal" uninstall of SupportAssist for Home PCs from Control Panel | Programs | Programs and Features or Settings | Apps.

Your suggestion to the OP greatdragao to try running the SupportAssistInstaller.exe installer while their antivirus is temporarily disabled might work, but if greatdragao requires further assistance it would still be helpful to know their Dell computer model, Windows OS, current SupportAssist version (if installed), etc. as requested <above>.

Hi kalatujj:

What version of SupportAssist, if any, is shown at Control Panel | Programs | Programs and Features, and has your Dell service warranty expired yet?

If my 18-Jul-2025 suggestion <above> to run SupportAssistInstaller.exe with Administrator rights doesn't fix your problem please let us know some basic information about your system like your Dell computer model, Windows operating system [open a Run dialog box (Windows key + R) and enter winver to find the version and OS build number], antivirus, and BIOS version.  To find your current BIOS version open a Run dialog box, enter msinfo32 to open your System Information, and look for the field named "BIOS Version / Date" in the summary.

The system requirements for SupportAssist v4.6.x and higher posted <here> in the current release notes also state that the Microsoft .NET Desktop Runtime version 8.0.x. *** is a pre-requisite. If that .NET Desktop Runtime is missing from your system try installing it manually (available for download at https://dotnet.microsoft.com/en-us/download/dotnet/8.0) and then restart your computer and see if the SupportAssistInstaller.exe installer runs to completion.

*** NOTE: If you have the correct MS .NET Desktop Runtime v8.0.x installed it will have the word "Desktop" in the program name but will be missing the word ".NET" as shown above.
