Here is my story... I installed TurboTax Deluxe 2019 in May, entered by license code and it worked. I started my taxes without issue. Then I started TurboTax Deluxe 2019 in July. It updated and asked me for my license code again. I reentered the same license code and got the dreaded Error 630. I tried to uninstall, reinstall and it didn't work. But finally, through another useful forum post, I tried a series of steps and think this is what worked for me:
I solved the problem this way:
I uninstalled TurboTax 2019 (via Control Panel -> Programs -> Uninstall)
I opened File Explorer: I went to c:\users\myname
I went to the View menu and deselected "Hidden Items" (so that I could see the AppData subdirectory)
I went to C:\Users\myname\AppData\Roaming\Intuit\TurboTax
I renamed TY19 to TYXX
I rebooted
I reinstalled TurboTax 2019 Deluxe
I entered the licence code and it worked.
Maybe I didn't have to uninstalled and reinstall TurboTax. I suggest you just try to rename the C:\Users\myname\AppData\Roaming\Intuit\TurboTax\TY19 directory first and see if that works.
If so, please post for all the other unhappy and frustrated TurboTax 2019 users!
