Thank you ee-ea. The FAQ didn't help. But I did read one comment (maybe two) on the community board that mentioned the renaming of the previous Turbo Tax program files as a way to solve the error problem. That eventually was the right path for me. Granted, I didn't figure it out by myself. I was able to get a hold of a customer service rep who helped walk through it. In a nutshell, you either have to un-install all previously installed TT software programs (for me, I had them all the way back to 2012), or simply rename each program file. There are two folders you would have to go into to do the renaming. I have an HP desktop with Microsoft Edge as the Op System. You would go into PC's C driver: 1. C: > Program Files (x86) >TurboTax, in which you renamed all the previously installed TT program files (you simply add a digit or an alphabet to the existing names); 2. Then C: > Users > Your use name > AppData > Roaming > Intuit > TurboTax, inside which you renamed all the previously installed TT files. With both done, you uninstalled your current year TT software to wipe it clean, then re-install it afresh according to the prompts. After updating the software and presented with a prompt to enter license code, you enter it and make sure all numbers/alphabets in the code are correct. Click Activate and, viola! Good luck!
Special thanks to Marcus the rep who had patiently walked through the process with me, through a few trials and errors. Compared with my customer service experience yesterday when the lady simply told me that the CD I bought was defective and I should go back to the store to get a replacement, which nonetheless didn't work, it was quite a contrast in terms of knowledge, expertise, patience and attitude.
