@TightLines Oh why do you need to install 2024? All you need is the tax data file ending in .tax2024 to transfer into the 2025 program. Did you file 2024? Do you need to open your 2024 return for something? You should have saved the pdf each year so you don't need the program to open the tax file.
What I would do on the old computer, is copy the whole Turbo Tax folder that is under your Documents. That should be where the .tax files and pdf files are stored. Also if you haven't done it, I would open each year in the program and save it as a pdf file, go to FILE - SAVE TO PDF so you don't need the program installed to view your return. Copy that folder to a flash drive or best yet is to burn it to a CD or DVD and then you will have a backup of them. Then on the new computer copy the folder (or files) from the flash drive to your Documents folder.
