My issue was turboTax wouldn't even install. Got to 3% and came up with options to try, which none worked. Called TurboTax, no help. Amazon, no help. It's the 2020 download. Here are steps I took to get it installed. My Laptop happens to also be my work laptop so I do have security software etc. installed.
windows 10 - Error during install, only gets to a few percent and stops with errors.
type "msconfig" in the search bar
In the System Configuration window
Select Boot
- Safe Boot and check Network
restart computer
At this point you can't install because the windows installer doesn't normally run in Safe mode
search "cmd" and right click on command prompt and (run as administrator)
copy and paste these following commands in the command prompt. Press Enter after typing each command line.
REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\MSIServer" /VE /T REG_SZ /F /D "Service"
REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Network\MSIServer" /VE /T REG_SZ /F /D "Service"
net start msiserver
Go back to where your Downloaded TurboTax file is.
Right click on the file and Run as Administrator
**IF the install is successful at this point you can change back to Regular boot**
go back now and type "msconfig" in the search bar
In the System Configuration window
Select Boot and uncheck "Safe boot"
Restart computer
good luck..
