Is your Dell service warranty still valid?

What is your Windows OS (if Win 10 or Win 11 please include version and build shown at Settings | System | About | Windows specifications and let us know if you have a Windows Home or Pro edition) and do you have the latest Alienware m15 R6 System BIOS v1.15.0 (rel. 08-Aug-2022) listed <here> on the support page for your Alienware model.  If you aren't sure open a Run dialog box, enter msinfo32 to open your System Information panel, and look for the “BIOS Version/Date” field.

When you go to Control Panel | Programs | Programs and Features what is the Dell SupportAssist version listed there, and is the .NET (Core) Runtime v5.0.17 (a new system requirement for the current SupportAssist v3.11.4.29 released on 23-Jun-2022) listed there as well?   From my Inspiron 5584:

Before you post back please read through samsuzzoha's 28-Jul-2022 SupportAssist Not Updating. There are several users currently having issues installing or running SupportAssist v3.11.4.29 and you might find some helpful information in that thread.

Hello!!! I instaled .NET 5.0 Runtime (v5.0.17) - Windows x64 Installer. And after this, the setup instaled SupportAssist like charm!
