SQL Server 2012 is not supported on Windows XP or Windows Server 2003.
In fact, Windows Server 2003 is the same as XP, just the server version.
As I and others have pointed out on this forum, Windows XP/Windows Server 2003/Office 2003 are end-of-life as of April 2014. Everyone should begin planning their upgrades now rather than later. If you upgrade to Windows Server 2008 R2/Windows 7 you can run the version of Amazing Charts you have now, then later move to Amazing Charts 6.5.
Proper planning and proper budgeting are the answer.
