Click Browse, and then navigate to the TurboTax CD on your CD/DVD/RW drive (usually Drive D).
Double-click the setup.exe file.
Click OK to launch the installer.
After installing, be sure to re-enable your antivirus and firewall programs before connecting back up to the Internet.
Reboot (restart) your computer.
Open TurboTax and run the updater.
