I didn't understand some of your post. So were you able to install and run last year's program for 2024? Or do you need to install 2024 now? Also for 2025 next year you will need Windows 11.
As I said above you can't exchange the Desktop purchase for the Online version. You would have to get a refund for it then pay for Online separately.
If you can't install the Desktop program or find another computer to install it on, you can use the Online version on Windows 10. You can transfer from this year’s Desktop tax return into the Online version next year. So be sure to have the .tax2024 file on your computer.
Then next year….You will notice several differences and may not like the Online version. It has less features and no Forms Mode. And you may need to use a higher version to enter certain things. You can only do 1 return per account. Your return is only saved online so be sure to save both the .tax2025 data file and the pdf file to your computer when you are done.
