Last evening, we reported about the public availability of Windows Vista SP2 and Windows Server 2008 Service Pack 2 (SP2).

Many users who have been using Vlited Windows Vista (Customized Vista) have been facing "Service Pack Installation Cannot Continue, one or more system components that the service pack requires are missing" error while installing the SP2. This problem occurs because system components that are required to install Windows Vista SP2 are not present on your computer.

If you too are in the same condition, you need to follow the below mentioned workaround to install SP2 on Vlited Vista.

To solve this problem, we need to do in-place upgrade, which requires your original Windows Vista DVD.

Warning: Before you perform an in-place upgrade, you should be prepared for a worst case scenario that results in your existing data on your computer being deleted. Backing up your system is recommended.

1. Insert the Vista DVD and wait for few seconds to load the autorun. If the autorun program does not open the Install Windows screen, browse to the root folder of the DVD and double click setup.exe.

2. When the "Install now" screen appears, click Install now. When you receive the Get important updates for installation message, do not click Go Online.

3. Click Upgrade when the “which type of installation do you want” screen appears.

4. Follow the on-screen instructions to finish the setup process.

Note: Once the upgrade process is finished, you have to activate your copy of Windows Vista.

5. You can then download and install Windows Vista SP2 on your machine (You must have a genuine copy of Windows Vista with SP1 installed on the computer prior to installing SP2).
