...I have .Net runtime 6.0.7 installed... Hi samsuzzoha: If I understand correctly, any application like SupportAssist v3.11.4.29 that is developed specifically for the .NET (Core) Runtime v5.x must have that same version of .NET (Core) Runtime v5.x installed [i.e., the application will not run correctly if .NET (Core) Runtime v6.x and/or v7.x are the only .NET Runtime(s) installed]. I can't explain why Dell would release a SupportAssist v3.11.4.29 update on 23-Jun-2022 that only works correctly with a .NET (Core) Runtime v5.0.17 that reached end of support on 10-May-2022 and will no longer receive security updates. In theory, if you do not have .NET (Core) Runtime v5.x installed on your system the SupportAssist v3.11.4.29 installer should automatically install that missing .NET (Core) Runtime, but that apparently isn't happening for many users. See my 03-Aug-2022 post in chriscfox's SupportAssist Won't Install for further information about installation of .NET (Core) Runtime v5.0.17. Before you try installing .NET (Core) Runtime v5.0.17 yourself, you might want to try a clean reinstall of SupportAssist using DELL-Chris M's instructions at SA Uninstall/Reinstall. Note that those instructions require the uninstall of all SupportAssist-related programs (including the Dell SupportAssist OS Recovery Plugin for Dell Update, Dell SupportAssist Remediation, etc, if installed) before SupportAssist is reinstalled. I've used those instructions a few times, and I go one step further and use Revo Uninstaller Free in Aggressive mode to uninstall each SupportAssist-related program to remove stray files and registry entries left behind by the "regular" uninstaller (Note: if you aren't familiar with Revo Uninstaller, the Dell Tech Support video at Dell SupportAssist Not Installing includes a list of folders, registry entries and Windows services that you can manually delete after your Control Panel uninstall of SupportAssist to get the cleanest possible reinstall). When I reinstall SupportAssist I always save a fresh copy of SupportAssistInstaller.exe (downloaded from the SupportAssist for Home PCs page) on my desktop, right-click the SupportAssistInstaller.exe file, and choose "Run as Administrator" - for some reason, choosing "Run as Administrator" is necessary on some systems (see Sidscrat's 04-Jan-2022 post <here> for one example).I also noticed that SH3H4Z posted on 04-Aug-2022 in SupportAssist - Installation Failed Message that they had to disable the real-time protection of their Microsoft Defender antivirus in order for SupportAssist v3.1.4.29 to install correctly. I don't know why the real-time protection of any antivirus would prevent SupportAssist v3.11.4.29 from installing but this might be something to keep in mind. As I said before, there are so many people having problems installing or running SupportAssist v3.11.44.29 right now - especially those with a Windows 11 operating system - that you might want to wait until Dell releases a newer SupportAssist installer with fewer bugs.  You can use the Dell Update Windows Universal Application v4.5.0 (released 22-Mar-2022) recommended on the support page <here> for your Inspiron 5570 to check for Dell software and driver updates, and if you ever need to run a hardware scan you can still run Dell's F12 ePSA (enhanced Pre-boot System Assessment) hardware diagnostics from your BIOS.---------------64-bit Win 10 Pro v21H2 build 19044.1826 * Firefox v103.0.1 * Microsoft Defender v4.18.2205.7-1.1.19400.3 * Malwarebytes Premium v4.5.12.204-1.0.1725 * Macrium Reflect Free v8.0.6867 * Dell SupportAssist v3.11.4.29 * Dell Update Windows Universal v4.5.0 * Revo Uninstaller Free Portable v2.3.9 * Inspiron 5583/5584 BIOS v1.18.0Dell Inspiron 15 5584, Intel i5-8265U CPU, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G NVMe SSD, Intel UHD Graphics 620
