When you try to install Windows XP Service Pack, you receive the error message "Access is denied" or "Service Pack installation did not complete"
When you install Windows XP Service Pack 2 (SP2) or Service Pack 3 (SP3), you may receive an error message similar to one of the following:
Service Pack 3 setup error. Access is denied.
Service Pack 3 setup error. Service Pack installation did not completeOr, the Svcpack.log file may contain the following error message:
These errors can occur if permissions for one or more registry keys are restricted in a way that prevents the service pack from updating the keys. Registry keys can become restricted by certain programs that change the system access control lists (SACL) in the Registry so that administrator accounts cannot alter them. The service pack installer runs under an administrator account (User), and therefore cannot access restricted registry keys. If Windows XP Service Pack cannot update a registry key because it is restricted by another program, the service pack installation fails.
To determine whether an update to the registry has failed, go to the "More Information" section.
Use the following troubleshooting methods in the order in which they are presented to resolve the issue. These methods are intended for intermediate to advanced users.
Note You must be logged on to Windows with a user account that is a computer administrator to complete these methods. If this is your personal computer, you are likely already logged on with an administrator account. If this is a computer that is part of a network at work, you might have to ask the system administrator for help. To verify that you are logged on to Windows with a user account that is a computer administrator, visit the following Microsoft Web site:
Method 1: Restart the computer, and then try to download and install Windows XP SP3 from the Microsoft Download CenterIf a program is running with a locked file, restarting the computer may unlock the file. To try to unlock the file, exit all programs and restart the computer. Then try again to download and install the service pack.
If you originally tried to install Windows XP SP3 through Windows Update and it failed, download the full Windows XP SP3 download package from the Microsoft Download Center. After you download the service pack, try to install it.For more information about how to download Windows XP Service Pack 3, click the following article number to view the article in the Microsoft Knowledge Base:

If this method did not resolve the issue, go to method 2.
Method 2: Restart the computer, and then close or disable any antivirus or antispyware program that may be runningWarning This workaround may make a computer or a network more vulnerable to attack by malicious users or by malicious software such as viruses. We do not recommend this workaround but are providing this information so that you can implement this workaround at your own discretion. Use this workaround at your own risk.
You can reduce the risk of attack by malicious users or malicious software by not visiting other Web sites or downloading files while your antivirus and antispyware program is closed or disabled.
One of the most common causes of installation failure is when a third-party program, such as an antivirus program, holds a file open or locks a file that the service-pack installer needs. To prevent this issue, follow these steps before you install Windows XP SP3:
- Exit all programs, and then restart the computer.
- After you restart the computer, close or disable any antivirus or antispyware programs that may be running.
Note You can disable the programs from the notification area. To do this, right-click the third-party program icon, and then click an option to close or to disable the application. If this option is not available, see the program documentation, or contact the program's manufacturer for instructions.
- After you close the antivirus program or the antispyware program, install Windows XP SP3 from the full download package that you downloaded in method 1.
- After Windows XP SP3 installation is complete, restart the antivirus program or the antispyware program that you disabled in step 2.
