How do I update TurboTax if I have the Desktop edition - the information in this help section is not helpful

[TurboTaxSusan]

When you launch the program, it should try to update. If it doesn't, you can select Help>Check for updates from the top menu. If that doesn't work you can reinstall the program using the download, which has the latest updates included in the file.

You can download the current version of TurboTax Desktop edition here:  Choose the TurboTax Desktop edition you need (for Windows). You can download older versions of TurboTax Desktop edition here: Where can I download the Desktop edition of TurboTax?
