I too am receiving "File Corrupted"
I sat down today to begin my taxes. I installed from the DVD purchased at Costco, then allowed the online update to occur.
I created a new return that had nothing but my name in it and saved, then closed TurboTax.
Reopen the just saved file ... FILE CORRUPTED.
Rinse and repeat 3 more times, same FILE CORRUPTED.
I looked at the "*.tax2021" file with a hex editor and saw that it is a ZIP container. I extracted the container contents of 2 files: "xxxx-xxx-xxx-xxx..." proprietary archive and "manifest.xml".
XML is structured text. "manifest.xml" is NOT text!
In any case, After re-installing many times I still get FILE CORRUPTED.
I tried to do an online install instead of using the DVD and TurboTax rejected it because it was already registered. Of course it was registered, I registered it!
