I tried all of these for days and many more suggestions that was listed on the community. I also called TT and spent 40 minites talking to them and they finally suggested using my laptop with Win 11 on it. What finally worked for me weeks later was starting my desktop in safe mode with networking. I was able to launch my tt deluxe and activate it. I then started it in regular mode and it updated and launched flawlessly.
Good luck all
