Get your taxes done using TurboTax

Thank you very much.
I have narrowed down my problem to a file prd.ini.signatures in the folder, C:/ProgramFiles/64bit. (This is the default folder the TurboTax2025 is installed.
When I launch TuboTax2025 it does not even go up to asking me to enter the license code to validate. If the program goes upto that point then there is no way the program can validate my license code, if I am disconnected from the internet.
It is great that some community members are good Samaritans and post the information that can help other members.
