Hi Sidscrat: I don't know if it's a coincidence, but I've recently noticed other Alienware users posting about issues reinstalling SupportAssist on their machines. See Sam Beavis' 13-Dec-2021 SupportAssist Will Not Install, who owns an Alienware Area 51M R2, for one example. I'm beginning to wonder if the Alienware Command Center software or some recent firmware/driver update that's unique to Alienware models is interfering with the installation of the current SupportAssist v3.10.4.18. If you haven't found a solution yet let us know your operating system (if Win 10 include the version and build shown at Settings | System | About | Windows Specifications, or type winver in the Run dialog box), antivirus, and default browser. Could you also confirm that you have an Alienware 17M - I couldn't find that model when I searched Dell Support at [URL] although I did find similar models like the Alienware M17, M17 R2, M17 R3, etc. Does the installation run to completion if you re-boot, download the SupportAssistInstaller.exe file from the SupportAssist for Home PCs page, save it to your desktop, and right-click and choose "Run as Administrator"? If you have a Win 8.x or Win 10 OS I'd also advise that you disable the Fast Startup power option and re-boot your system. If you use Win 10 that power option can be found at Control Panel | Hardware and Sound | Power Options | Choose What the Power Buttons Do | Shutdown Settings | Turn on Fast Startup - see Option #1 of the TenForums tutorial How to Turn On or Off Fast Startup in Windows 10 for further details. Fast Startup (also known as hybrid boot-up / hybrid shutdown) can interfere with the loading of services at boot-up and cause all sorts of unexpected glitches and strange behavior.  Fast Startup can even interfere with Windows Update - see the MS support article Updates May Not Be Installed With Fast Startup in Windows 10 - so I don't know why Microsoft still enables this power option by default.

Instead of uninstalling from Control Panel | Programs | Programs and Features I usually uninstall my Dell programs with Revo Uninstaller Free in Aggressive mode to try and clean up any stray files and registry entries left behind by the built-in uninstaller. Here are the SupportAssist-related programs currently installed on my Inspiron 5584:[IMAGE] -----------64-bit Win 10 Pro v21H2 build 19044.1415 * Firefox v95.0.2 * Microsoft Defender v.4.18.2111.5-1.1.18800.4 * Malwarebytes Premium v4.5.0.152-1.0.1538 * Dell SupportAssist v3.10.4.18 * Dell SupportAssist Remediation v5.5.0.16046 * Dell Update for Windows 10 Universal v4.4.0Dell Inspiron 15 5584, Intel i5-8265U CPU, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G NVMe SSD, Intel UHD Graphics 620
Hello all. SupportAssist is giving me headaches. I had it installed on my Alienware 17M. There was an issue with it so I uninstalled it and now can no longer install it. I get a message: “We were unable to complete the installation. Please reboot your PC and try again.” I can reboot but the same error occurs. I have already tried several "solutions" to no avail. They are: Dell Support Video Solution Community 1  None of these methods works. I have removed every folder and edited the register exactly as instructed and it will still not install and gives the same error message. Why can we not install a program that was just uninstalled? I know this is a common problem so hopefully there is a good solution.
