Error 209 could indicate that your anti-virus software (or an actual virus) is blocking your TurboTax installation.

Try disabling all anti-virus programs (including modem), update Windows, then try your install again.

Make sure you install/run on your C drive, and if you're transferring a 2023 file, it's also on the C drive. 

If you have Windows 11, here's more info on How to Switch Out of 'S' Mode for Windows 11 and more tips for Troubleshooting TurboTax Desktop Issues.
