This happened to me when I purchased TurboTax premier 2024 from Costco 's online website. It took them about an hour to send to me an email with the license code. When I typed in the license code into the TurboTax activation screen, I got the 630 error. I called TurboTax support and they weren't able to help, and said that they were seeing a lot of problems from customers who purchased from Costco and Sam's club.
The problem eventually got fixed after I rebooted my computer. I'm unsure if this did anything or just caused a longer pause until TurboTax and Costco could get their systems in sync.
Very frustrating experience.
