Turbotax Home and Business 2024 : Failed updates

[amyonghwee]

For TT home and business 2024, today 3/20/25, I tried to install updates. Encountered "Microsoft Installer error :1603". I installed manually using w_perrelsuperpatchIS_ttax_2024.exe and it says success. Then I rerun TT, the same error 1603 is shown. I clicked OK and it says "Restarting Turbotax"  and then nothing happens..

Pls help as I am not able to run TT...

I retried again using manual updates. And able to restart TT Home and Business 2024... strange... but it works now,
