Run the installer as an administrator by right-clicking the file and selecting "Run as administrator." If the installation fails, uninstall any previous TurboTax versions and clear temporary files. Reboot your computer before trying again. Make sure you download the official version to avoid corrupted files—search how to download turbotax from the official Intuit website.
