2020 TurboTax updater fails with Microsoft Installer error 1603

Interesting. Was your download from TT or a 3rd party?

2020 TurboTax updater fails with Microsoft Installer error 1603

Interesting as they told me the issue was related to 3rd party cd's. I will admit they had me download Premier (I had Deluxe) so now I'm wondering if that is part of the problem.

 

You are correct, you can download as many time as necessary.

I am having problems trying to transmit my taxes.  It tells me I need to update first, but I keep getting an error 1603.  It will not let me bypass it.  HELP

Try again after a restart. If that doesn't work contact TT. As I posted above, they had me uninstall and then install a download they provided. Phone support opens at 5am Pacific time and I was able to get through almost immediately by calling then.  https://support.turbotax.intuit.com/contact/

Yes, @FortFun is correct. To contact TurboTax, see: What is the TurboTax phone number?

 

Error 1603 is an error that can be resolved. 

 

For more information, see: Error 1603: "A fatal error occurred during installation or updating".

Started  TurboTax 2020.

Please fix this soon.

AS I HAVE SAID BEFORE:::

this is what i had to do to get mine back up and running for now till I get forced to do another update that may go nuts again they should put in an option at this point letting us decide to update or not . i prefer to download my updates and run them myself .

EbonyA,

 

I for one had tried (multiple times) the steps in the FAQ to no avail. The new download of the complete TT program was  the only solution that worked.

Thanks! ThT worked perfectly and I was able to update. I know there is supposed to be a bug update coming up as soon as Friday with all the changes caused by the stimulus. Hope it works.

I have done what your update says - download the manual update to my desktop and ran it.  I rebooted several times.  I'm running AVG software and I've checked that and it's not blocking it.

 

Help!  I need to do my taxes and trying to do my adopted grand daughter's taxes!!!

 

Used Turbo tax for 15+ Years and never had this much trouble PLUS this years version - which I'm pretty sure is up-to-date on my computer since I installed and updated last weekend with NO PROBLEM - usually has a by pass method to skip.  We got all the way to the CHECK MY TAX and that's when this all happened.

Did you do a uninstall, reinstall from the administrator account?

@JHtaxes,

 

Although I had posted what I thought was a solution, my TT did the same to me when I was ready to do the final check before filing. I was able to perform the update check and file by running the program as Administrator. Try that and best of luck!

no  my microsoft windows 10 user has administrator rights.  to find out if you have admin rights, search the windows box at the left bottom of the home screen and follow the instructions.
