Hi Peter,
TurboTax seems to have a variety of problems this year with activations. I purchased a download version from Costco, as I've done for several years now. It installed fine (Windows 8 64-bit), but the licence key activation window never opens, so I can't activate it. Have spoken to tech support twice. First one didn't have any answers. Second one blamed it on my McAfee security software, but I uninstalled McAfee and reinstalled TurboTax 2020. It still wouldn't work. I think they have enough issues trying to get it to work with Windows 10 that they don't even care about anyone still running Windows 8, which they advertise as being compatible by the way.
I've been trying since January and still can't get the Licence Code Activation Window to open, so TurboTax is no good for me this year. I returned it to Costco for a refund and went with another tax software that works just fine.
Good luck!
