Just as it was the case with Service Pack 1 for Windows Vista RTM, the integration of Service Pack 2 into the operating system is not always a smooth and streamlined experience. In fact, even with the Beta of Windows Vista SP2, Microsoft has warned of installation problems related to the deployment of both the standalone and update packages of the service pack. With the Windows client and server operating systems joined at the hip since the release of SP1, scenarios involving failed installations of Vista SP2 Beta have also been valid for Windows Server 2008 SP2 Beta. “Installation was not successful” is the error message produced when the process of integrating the SP2 Beta bits into Vista SP1 or Windows Server 2008 fails.

“When you try to install the stand-alone package for Windows Vista SP1, Windows Vista SP2 Beta, or Windows Server 2008 SP2 Beta, you may receive the following error message: 'Installation was not successful,'” Microsoft revealed, informing that the deployment of SP2 via Windows Update could also fail and deliver similar symptoms.

In this context, the first step that needs to be taken when troubleshooting failed installations of SP2 Beta for Vista and Windows Server 2008 is to use the standalone package for the service pack. “One reason why you may want to use the stand-alone package for the service pack is that you can eliminate installation issues that may be related to Windows Update. This simplifies the troubleshooting process,” Microsoft added.

For both 32-bit and 64-bit versions of Vista and Windows Server 2008, Microsoft is offering the System Update Readiness Tool. The utility is designed to repair an inconsistency in the Windows servicing store. If an issue in this service is indeed at fault for the failed installations, future updates, service packs, and additional pieces of software may fail to install. In this regard, the System Update Readiness Tool for Windows Vista SP1 and Windows Server 2008 will resolve any problems with the operating systems' update architecture.

At the same time, SP2 Beta, just like SP1, fails to play nice with some security solutions. Another troubleshooting approach involves closing “all applications, and then restart your computer. After your computer has restarted, disable any antivirus or any antispyware applications that may load during the startup process. As soon as you close the antivirus or the antispyware application, try to install the full download package for the service pack,” Microsoft advised.

However, simply turning off security programs might not be sufficient, and SP2 Beta will continue to fail installing. In this regard, the complete uninstallation of all security applications followed by a restart might just do the trick and allow for Service Pack 2 Beta to be successfully integrated into Vista SP1 and Windows Server 2008 RTM/SP1.

At the start of December, Microsoft made available for download the standalone package for Vista SP2 Beta and Windows Server 2008 SP2 Beta, but also the standalone DVD ISO bits. Of course, SP2 Beta is also available through Windows Update, via the Windows Update Experience Kit.
