What is the error message that you are getting?

FYI: You don't actually need TurboTax 2024 installed to transfer your return into 2025. You only need to have your .tt24 file.

It took my activation code once but wont open again

@kamloopsjoe Are you using TurboTax Desktop 2024? If so, try the following:

• Go to C:\ProgramData\Intuit Canada and check for umid file
• If umid file exists then open a file "C:\ProgramData\Intuit Canada\tt2024\TTConfig.ini" and enter UseCustomUMID=1 at the end of file
• Close and save TTConfig.ini
• Restart TurboTax
• TurboTax will launch with previously activated licence
