I spent 90 minutes on the phone with a TurboTax tech rep yesterday and we were unable to solve the problem. I later tried the same download procedure using my wife's notebook. The downloaded file and installation proceeded without incident. I then copied her downloaded file to a flash memory, and ran it on my own computer - it also unzipped and installed without incident. The problem seems to be that the download file on my computer was being attacked by anti-malware program even though we had turned off my Windows Defender anti-malware, firewall, anti-virus and any other modules we could disable. I have no idea what was "protecting" me during the TurboTax download. I also have System Mechanic Ultimate Defence on this computer but it is not resident in memory and runs only when I execute it. It is not an issue with bios, cache, cookies, windows up-dates, the registry....... all of which are clean or up to date. In any case, my course of action may provide a solution to others facing the same problem.
