Hi. Thank you very much for the information on the error. In your attached paper the analysis was spot on. The solution was correct as well to disable the FIPS algorithm. But the steps to disable on my laptop were different. I had to directly update the registry for a key. Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\FipsAlgorithmPolicy . I changed the value from 1 to 0. Then I restarted my computer, and the California update installed successfully. Appreciate your quick response. Regards, Shashank

I am having this same issue, can you provide more details for updating the registry for a key?

leonhg88:  NOTE:  If you are not familiar with how to update the registry, I recommend you locate someone who is because one mistake can seriously mess up your computer.  To get to the registry, right click on the Windows icon on the lower left of your display and select "Run".  In the "Open:" area, enter regedit and click OK.  Now navigate to the key in the above comment and change the value for the "Enabled" key from 1 to 0.

You are commenting on an older thread that does not relate to this issue. However, you can work on Turbo Tax using different platforms but you cannot use different platforms at the same time.
