Intuit's Statement regarding QB 2006 and earlier NOT compatible with MS Vista:
Since QuickBooks 2006 and earlier versions were developed
and released before the introduction of Windows Vista,
these versions may be adversely affected when used on
a computer running Windows Vista.
This will impact Simple Start, Basic, Pro, Premier, Payroll and Point of Sale, as well as other QuickBooks products and services. We recognize that your QuickBooks software is an important business tool and apologize for any inconvenience this may cause you.
WHAT YOU SHOULD DO TO STAY UP AND RUNNING ON QUICKBOOKS
• If you do NOT upgrade to Windows Vista No action is required. If you plan to stay with your existing Windows operating system (for example, Windows XP or Windows 2000), you can continue to use your current QuickBooks products.
• If you choose to upgrade to Windows Vista - We recommend that you use QuickBooks 2007 (and Point of Sale v6.0, if applicable). QuickBooks 2007 is the only version of the software built to run on the new Windows Vista operating system.
