You can use QuickBooks up to 30 days without registering. After 30 days, you must register. If you have multiple copies of QuickBooks, you must register each copy. If you install QuickBooks on a new computer, you need to register again.

Important: In keeping with Intuit's discontinuation plan for older products, discontinued products cannot be registered for the first time. You may re-register discontinued products if they have been registered previously and are being reinstalled. Just follow the steps above and choose the Phone option. Assisted support for discontinued products is no longer available. If you have an discontinued product, we recommend that you upgrade your version of QuickBooks.
