TurboTax update fails with Windows updater code 1603. Specified steps to address this by downloading manual update and troubleshooting .NET Framework did not solve the problem. Was able to work on taxes by bypassing update and that was ok until trying to submit/file the taxes. There was no option to bypass the uptate there. Two long sessions with support did not resolve the issue. Support supposedly filed a critical item with engineering and also referred me to the JustAsk site for other ideas. No joy. I was able to complete the taxes because we have another computer, same configuration, where the updates were successful and able to file the taxes. After many years of using TurboTax I may have to rethink for next year..
