It can often be due to a USB drive.
If you have a USB drive/device plugged into a USB port at the same time you are launching TurboTax, then remove the USB drive/device. Then try launching the TurboTax program again. See if that solves the problem.
Or try it the other way around. i.e., if you had a USB device plugged in initially when you installed TurboTax originally, but don't now, then plug it back in and try.
