Hi, I purchased a new PC and am trying to reload my 2023 online version.
I got it installed, but it's NOT letting me activate it with my 16 digit code from last years purchase; It says 'All available activations for that code have been used. Error code: 603)
How do I reactivate my 2023? I have 2024 installed & ready to go, but need some changes to my 2023 files. Please let me know
