Intuit Tech Support worked me through the issue. Even though I was running under administrator, we had to allow these rights specifically to Turbo Tax to get the installer working. Even though Turbo Tax was running okay, its installer would not run under W10 without specific rights. I now have it running with all updates and my state download. Tech Support indicated they would notify Intuit to update their support page as it currently pertains more to an installation problem when it is more of a W10 access issue.
