You cannot install ATA version 1.6 directly on top of ATA version 1.4. You must install ATA version 1.5 first. If you accidentally attempted to install ATA 1.6 without installing ATA 1.5, you will get an error telling you that A newer version is already installed on your machine. You must uninstall the remnants of ATA 1.6 that will remain on your computer - even though the installation failed - before you install ATA version 1.5.

Follow these steps to update to ATA version 1.6:
