So... I think it may be working now. This morning, I followed the instructions on the link below and did a clean uninstall/reinstall. The only difference I made from the instructions was that I uninstalled both the SupportAssist and the Dell Update.SupportAssist for PCs and Tablets Clean Uninstall and Reinstall Having now reinstalled the latest versions of both, they both appear to be working: BIOS and SupportAssist OS installed; Dell Update is working; and SupportAssist seems to finally accepted that I've already re-upped my warranty. I'll be back to kvetch should anything else go wrong, but as of now, I'm will to consider the matter resolved.
I have an Inspiron 7591 2n1 running the latest version of Windows 10. Earlier this week, Dell Update alerted me that I needed to install two critical updates: Every single time I've pressed Install, I get the same response: "0 of 2 successful. 2 updates failed." I tried installing through SupportAssist, but the only optional update is the BIOS one, which only offers the option to "install manually". When I click on it, I only get the three dots you see when you're waiting for someone to reply in a chat. I went to the Dell site to download and install them on my own, but the SupportAssist keeps telling me that it's already up-to-date and the BIOS .exe won't open. At all. ON TOP OF ALL THAT, SupportAssist keeps reminding me that I need to update my warranty, which expires in a few days. I repaid my warranty two days ago. I know someone at Dell must know this because when I click on Renew in SupportAssist, it takes me to an online invoice showing, yup, I already paid for an updated warranty. Yet, SupportAssist continues to have the "Warranty ending soon" notice at the top. Now that I've vented... what the solution to all of this?
Dell Update won't install critical updates, warranty confusion
