Thanks for the suggestions. Unfortunately I've already tried most of those things.
I called support and it sent me to Troubleshoot installation and running TurboTax for Windows (intuit.com). I've already tried much of that list too.
I guess it's time to look for new software. I do four family members' returns with TurboTax Deluxe. Using TurboTax Online, which charges separately for each return, would be very expensive for me.
