If you install Service Pack 4 for Microsoft Dynamics GP 2010, you cannot upgrade to Microsoft Dynamics GP 2013 until the release of the US Payroll Year End Update in Mid-November.
Note: Please do not post questions about technical issues in the comments, you would be best to post on the newsgroups (links in right hand panel) or create a support incident.
Thanks to the development and support teams for their work in getting Service Pack 4 released.
