Here is a list of QB products for supported and non-supported versions.
Products affected by service discontinuation as of May 31, 2011, are listed in the table below. If you don’t make use of live technical support or any of our add-on services, and are happy with your current version of QuickBooks, you can continue to use it.
If you are using a product affected by service discontinuation and want to maintain access to live technical support and add-on services, you’ll need to upgrade to the latest version of QuickBooks as soon as possible.
As services to older versions are scheduled to be discontinued, we notify affected customers in advance by mail or email and through in-product notifications and information on this web site, such as this article. Please keep an eye out for updates on our future plans as they become available.
