This error can occur when the Microsoft .NET Framework Installer can't install and/or update your system. Possible causes include:

• Damaged Windows file and folder permissions

If error 1603 occurs while updating TurboTax, download and install a manual update.

I had the same problem and tried all of the help listed on your site.

Chkdsk

Disk repair

netx repair

antivirus off

Your manual update link was non-functional by the way

I even tried a Turbotax repair on the install/uninstall programs

I finally uninstalled an re-installed Turbotax which corrected the problem

I had the same problem yesterday and called TurboTax for help. The rep first thought it was a problem with my computer. I pointed out that a lot of people are having the same problem. We tried a few things (like disk defragmenting) and eventually uninstalled TurboTax. And then reinstalled from my CD. Updates worked and everything seems okay for now.

Yes, uninstalled and reinstalled 2020 Premier download and it works, so far

Same problem for me with Deluxe CD version.  I went to the TurboTax site and sought to download another copy.  When I started the download, it told me I had to uninstall the previous version or REPAIR the current version.  Chose REPAIR, waited 15 minutes, Repair was "successful."  And everything worked fine after that.  By the way, I tried disconnecting my computer from the internet - didn't work.  Try the REPAIR function, it worked for me.

THe OPTION that says the computer is messed up Does not work - The only solution found by real people is to uninstall TT then reinstall it from the CD and then the updates work fine - I hope the next update works, but at least I know how to bypass the TT software problem (unfortunately  an employee sent me down this path AND I wasted many hours trying all those things my computer has never been healthier and the stress from this bad advice is enough to give up on using this software next year).  Quit blaming this recurring problem on our PCS.

I'm having the exact same issue. Tried everything from restarting router, closing all programs etc. Still looking for a fix.

I had this problem in March of 2021. The solution then was to uninstall TurboTax. And then reinstall from my CD. Updates worked and everything was okay. If that didn't work for you, I would call TurboTax. That's what I did last year.

Uninstall Turbo Tax and reinstall (as an Administrator). Worked perfectly!
