Here is what worked for me:   Uninstall via "Revo Uninstaller Pro (Trial)" or "Advanced Uninstaller Pro (Trial)" Download from the author's website, no where else, please. A simple uninstall process from control panel or windows settings is not sufficient. Allow one of these apps to aggressively uninstall, remove associated folders, and delete associated registry keys. Even afterwards, we have to verify everything is entirely uninstalled. If you don't see it installed, check for next item on list.   Before doing anything else, continue by deleting some folders manually which were unable to be removed otherwise, and if you don't see the folder, check for next item on list. Copy/Paste the filepath because some folders ARE hidden.  Before doing anything else, continue by opening your Start Menu by clicking the Windows icon on the bottom left of your screen. Type "Regedit", right-click it, and select to "Run as Administrator". You need to delete some registry entries manually which were unable to be removed otherwise, and if you don't see the folder, check for next item on list. Copy/Paste the filepath to save time in the search. Before doing anything else, continue by rebooting the computer immediately.  **Now, please relax and allow this to be a slow process**   This is a combination of solutions sourced from Dell Community, and the major contributor is from Martin Schiemenz (Dell Enterprise Support Services) comment on 04-29-2019 to the following post:  [URL]  It was also a major contributor to see how deep the rabbit hole goes in the following community post:  [URL]#M91454      I obviously came up with some steps of my own toward the end after a couple dozen hours of trial and error attempting what others were successful trying. It is apparent that everyone's computer is different so I performed these exact steps as a sort of "FULL SWEEP" after understanding the underlying problem. Dell Update is more of a plug-in for SupportAssist which is the main engine behind the process running into error conditions due to possible Windows Store trying to install the MS APP version along-side or instead of the .EXE or .MSI version which is downloaded from the Dell website directly. That download is the most maintained version and is specifically for HOME PC. You will want a ENTERPRISE PC version if you have Windows Enterprise OS rather than Pro or Home.    I do not work for Dell or Microsoft, I am just a technology-enthusiast offering my personal solution to anyone who hasn't found success yet in troubleshooting with other suggested routines online.
