Get your taxes done using TurboTax

I was getting error 1603. I tried a number of things. I turned off anti-virus. I ran as administrator. I manually installed the update from a download. I repaired the install. Ran other software to fix broken registry items, etc...

 

What finally worked was un-isntalling and re-installing the Turbotax software. After re-installing, the update worked and I was finally able to continue using Turbotax.
