The problem was the windows security app, which prevented access to the hard drive due to virus concerns. I got in the security app and allowed the Turbotax app...

If I try to update software, I must save the file first, and I cannot save the file because "file not found."

I just downloaded TurboTax Home and Business. When i try to save new file or exit I receive a "File not found. Check the file name and try again" message
