Trying to start TurboTax 2021, Home and Small Business, it wants to update. Going thru the process, I get, "Failed to install update. Microsoft Installer error 1603, Faltal error during installation.
I tried restarting Windows.
I disabled Windows built in firewall and antivirus.
I started TurboTax as administrator.
I updated Windows 10.
I downloaded and ran dotnetfix.
I ran sfc /scannow as administrator.
I downloaded and ran the manual update.
I pulled the ethernet cable out of my computer but it still wants to update.
I called Intuit and asked for a call back. They said roughly 45 minutes. In roughly 45 minutes I got a call back from a recorded message that said to check their website for help. Ugh. I had been doing that for a long time! Frustration.
Anyone got any ideas to try?
