Hi

Here is the FAQ on that SP3,

The following instructions will allow Studio 11.0 to properly install on a computer with Windows XP Service Pack 3 installed.

The version of Windows XP Service Pack 3 - Beta that was tested with these instructions was the release candidate version 3264.

Note: These instructions are only for new installations of Studio 11.0. If a system is upgraded to Windows XP SP3 while Studio is installed, Studio will continue to work normally.
