I have a 2012 tax file I can't open due to tax2012 file extension. Thank you
2012 is unlikely to work on a modern computer, and any CD might not have the program updates.
And the TT licensing agreement only permits the original owner to install it on their own computer(s).
OR you could try the TaxPrinter service to convert a .tax file to pdf at

They might be expensive and it is probably not safe to email tax returns back and forth. They are not related to Turbo Tax.
