How to resolve error code 603? No more than 5 activations have been installed

When opening TT2024 today I was surprisingly presented with an activation screen requesting the activation code. When attempting to enter, received error code 603, “5 activations have already been registered”. I have not exceeded the allotted 5 installs. Appreciate any guidance to resolve the issue.

i had a similar issue (with me nothing below worked and I did not try system restore or restore from image) what worked was that I back up files and folders. I had a backup of the below folder which included the two .json files. I copied them to the designated folder and then relaunched Turbotax. It worked.

if these don't work try the following

1. Search C:\Users\( your user id)\AppData\roaming\intuit\turbotax\

2. Click into the TY2X folder
3. Delete the two .json files and try launching TurboTax again

note appdata is a hidden folder so you will have to go into a folder and on the view tab in the show\hide section check "hidden folders"

try support to see what it will do for you.

as a last resort other things that might work (i have never tried system restore) but it does have some risk) system restore

2) restore from a disk image. This puts the drive back to what was on it when the image was created.
