In the eventuality of a failed installation of Windows XP SP3 RTM Build 5512, there are some troubleshooting steps end users can take before running to Microsoft Support for help. The troubleshooting methods involve nothing more than basic actions on the part of the end user and are designed to resolve an unsuccessful installation process while, at the same, time ignoring the error message.
First of all, Microsoft advises all end users to turn to Windows Update for the primary source of the gold bits of XP SP3. “Sometimes an installation is unsuccessful because a previous operation was not completed. By restarting the computer, you close any pending computer functions and restart the process. Wait until the computer finishes the restart process, and then log on to your account. Visit Windows Update to reselect and install Windows XP SP3. Click Express Install (Recommended),” Microsoft stated.
If the Windows XP machine that the end user is trying to update meets all the requirements for XP SP3 RTM, the service pack will be automatically installed. At the same time, if the WU package fails to install, users also have the possibility of manually accessing the bits for XP SP3 and then to attempt to integrate the service pack in their operating system.
