Doing a manual update for TurboTax Desktop should resolve Microsoft Installer Error:1603.

 

Please follow the directions in this TurboTax Help Article: Manually Update TurboTax for Windows Software

I am using TT desktop and getting the same error 1603.  Manual update didn't work.

 

Thank you.

You need to clear your Cache and Cookies before doing the manual update.

 

What is a manual update?
