This issue was never resolved for me. However, I believe I have been able to circumvent the problem. When I first called Turbo Tax, they told me the software was not ready for general use yet, so that may be why it would not install. I was able to install the same download on another computer, so I was confident this is just a setting on my computer, but no idea what setting was preventing the install. I also waited a while to call TurboTax back so the software would be generally available. I worked with TurboTax for some time on November 29, but we did not resolve the issue. TurboTax insisted it was a Microsoft issue and that I needed to call Microsoft. In my opinion, calling Microsoft would have been expensive and a waste of time as there was no indication from TurboTax where they were failing in the process. I told TurboTax that if I were Microsoft and someone called me saying their application would not install, the first thing I would ask is what is it failing with or where is it failing in your install. TurboTax had no answer for that and offered no way to trace where or why it was failing.
So, my circumvention: I have an Admin user account on my personal PC. I copied the downloaded file to a common location on the C drive. I then switched to the ADMIN user, ran the install without issues, then switched back to my personal account and all appears to be working OK. I have been able to update TurboTax from my personal account, but just cannot install it. I still have no idea what settings may be different on my personal account, preventing the install, but TurboTax is the only program giving me an issue. While working with TurboTax they did try to have me install some "glance" software so they could view my PC, but that failed with an error. So, with TurboTax simply "going away" when I tried to install and "glance" getting an error when trying to install, TurboTax support indicated I had a Microsoft problem and needed to call them. I do agree, clearly something is different on my user account. I do not agree it is a problem to any software other than TurboTax. And, I suspect others will have a similar problem to mine. If so, you may be able to resolve your issue as I did. Hopefully, I have no further issues with the install I have in place now.
