Hi chriscfox: The short answer is "Yes". The .NET (Core) Runtime v5.0.x is a new system requirement for the latest SupportAssist v3.4.11.29 (rel. 23-Jun-2022). You started this thread in Dec 2021 back when SupportAssist v3.10.4.18 was the current version so please note that ACryinShame's comments <above> about the Dell TechHub (a new service bundled with the SupportAssist v3.4.11.29 installer that is now required to run hardware scans) and their missing .NET Runtime v.5.x are specific to installation problems with the latest SupportAssist v3.11.4.29. Also note that older "classic" .NET Frameworks (for Windows PCs only) are completely different than the newer .NET Core Runtimes (multi-platform for Windows, macOS, Linux, etc.).  See the geeksforgeeks article Differences Between .NET Core and .NET Framework and Microsoft's .NET and .NET Framework., which notes that newer .NET Core Runtimes are now simply referred to as .NET Runtimes.  In fact, the minimum system requirements <ADMIN NOTE: Broken link has been removed from this post by Dell> for the latest SupportAssist v3.11.4 state that you must have at least "Microsoft .NET Framework 4.7.2 and .NET Core Runtime v5.0.14". See my 16-Jul-2022 post in DavG94's Dell Support Assist Fails to Install for further information about the .NET (Core) Runtime v5.x. 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]. You would have to ask Dell why they released a SupportAssist v3.11.4.29 installer on 23-Jun-2022 that will only work if users have installed a .NET (Core) Runtime v5.0.17 that reached end of support on 10-May-2022 and will no longer receive security updates. According to the SupportAssist v3.4.11 release notes <ADMIN NOTE: Broken link has been removed from this post by Dell> the latest SupportAssist installer should automatically download the .NET Runtime v5.0.x if it is missing from your system but that apparently isn't happening for many users. I'm not the best person to ask how to install .NET Runtime v5.0.17 - for some reason, Windows Update automatically installed KB5013354 [the 64-bit .NET (Core) Runtime v5.0.16] on my Inspiron 5584 during my April 2022 Patch Tuesday updates, but I still have no idea why - as far as I know there was no software installed on my system back in April 2022 that required a .NET (Core) Runtime. You can still find installers for .NET (Core) Runtime v5.0.17 at [URL] - just expand the "Out of Support Versions" section and select ".NET 5.0".  I'm not certain which exact v5.0.17 Runtime installer you need to download from [URL] - I'm guessing ".NET Desktop Runtime 5.0.17" is the best choice, but I'd double-check with Dell employee  [NAME]  or someone else who's more familiar with .NET (Core) Runtimes just in case the the smaller ".NET Runtime 5.0.17" is all you need. Here's what Windows Update installed on my Inspiron 5584 / Win 10 v21H2 machine, and my SupportAssist v3.11.4.29 seems to run as expected: [IMAGE] I personally don't like SupportAssist - it's too buggy, consumes too many system resources, and the "system optimization" scans (Clean Files / Tune Performance / Optimize Network) are too aggressive and have the potential to do more harm than good - see my 12-Jul-2021 comment in ex-jedi's Prevent Automatic Recycle Bin Emptying. I have disabled my Dell SupportAssist and Dell TechHub services so SupportAssist can't launch automatically on my Inspiron 5584 at boot-up, and I've started using Dell Update v4.x to check for Dell software and driver updates. There are so many people having problems either installing or running SupportAssist v3.11.4.29 right now that it might be best if you simply wait for Dell to release a newer version that installs correctly and has fewer bugs.-----------64-bit Win 10 Pro v21H2 build 19044.1826 * Firefox v103.0.0 * Microsoft Defender v4.18.2205.7-1.1.19400.3 * Malwarebytes Premium v4.5.11.202-1.0.1716 * Macrium Reflect Free v8.0.6867 * Dell SupportAssist v3.11.4.29 * Dell Update Windows Universal v4.5.0 * Fusion Service v2.0.58 * 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
My SupportAssist wasn't loading properly, so I followed the instructions to uninstall and reinstall it. Unfortunately, it won't reinstall. I click on the download link, then click on the file it downloads. It tells me it is downloading files and quickly counts up to 100%. Then it changes to "Getting application files" with a message that "Downloading and installing start-up files" and another that "depending on the speed of your PC, this installation can take several minutes". But it just sits there for hours. I've tried it a few times with the same result. Any ideas?
