With a single-user license, you can install QuickBooks on 1 computer and on 1 additional portable computer (e.g., a laptop that you own and use in your business) as long as both devices are used by the same person. ONLY that specified person can access and use QuickBooks on both computers.
To install QuickBooks on 1 additional portable computer, follow the instructions for installing QuickBooks Pro or Premier 2013, 2012, 2011, 2010, 2009, 2008, 2007, or 2006 and earlier.
Use the same installation numbers you used on your original installation. Follow the on-screen instructions when QuickBooks prompts you to register the second installation.
If this solution does not resolve the issue, you can read discussions and post messages and questions relating to your issue on the Intuit QuickBooks Community site for free or you can contact a technical support agent for additional guidance. Fees may apply.
