So sorry you are having such horrific problems courtesy of TT.
I am not a computer or cyber geek, just a very long time user. But after this year I probably won't use TT anymore as in the time I spent trying to activate I could have done my taxes by hand even though I have a complex return, plus over the past few years there have been numerous problems with TT incorrect forms and glitches not being fixed until just before tax day which forced manual overrides and/or amended returns. I now cringe every time I have to open TT wondering if there is going to be a problem using or updating (just checked my own install again and it seems to still work thankfully but who knows next time). And I looked into other tax sw but found numerous problems reported for those as well.
The problem many of us on this thread were/are experiencing was trying to activate the TT sw after downloading. TT just put us in an endless login loop when trying to activate with the activation code for desktop sw. From your previous message and your possibly getting a different message at an apparent different point in the process, I am not sure of your situation so sorry to ask these questions to clarify:
It sounds like your problem may be somewhat different? Are you using a desktop version of TT or the online version? Were you able to successfully download the sw and activate and now are not able to log in and being put in an endless login loop trying to open TT sw that has already been successfully (LOL) installed and activated? What version of windows are you using, what firewall and antivirus are you using (hopefully something different than what MS windows provides).
Not sure if you have read my previous posts re the endless activation loop, but I tried all of what you did many times wrt reinstalling, running as admin (which I did from beginning), clearing browsers, using different (4!) browsers, adding as trusted site, deactivating firewall and antivirus (not recommended and if you do then before make sure to create restore point and running disinfection sw afterwards). I am running Windows 10 Pro 64 bit version with third party antivirus/spamware/ransomware/firewall plus third party vpn. So if you are on Windows 11 and/or using MS Defender etc what worked for me might not work for you. But if you haven't tried my posted solution, hopefully it might work for you as well but there are no guarantees. It did not work for someone else.
