Prerequisites
No prerequisites are required.

Restart requirement
You must restart your computer after you apply this hotfix.

Hotfix replacement information
This hotfix does not replace any other hotfixes.

File information
The English version of this hotfix has the file attributes (or later file attributes) that are listed in the following table. The dates and times for these files are listed in Coordinated Universal Time (UTC). When you view the file information, it is converted to local time. To find the difference between UTC and local time, use the Time Zone tab in the Date and Time item in Control Panel.



WORKAROUND
This workaround applies to Windows Server 2003 and to Windows XP.

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

To work around this problem, change the PolicyScope registry value to 1 before you try to install the package. To do this, follow these steps.

Note If the computer is joined to a domain, a domain policy update may override the registry changes that you make. We strongly recommend that you disconnect the computer from the domain before you follow these steps.  Click Start, click Run, type regedit, and then click OK. In Registry Editor, locate and then click the following registry key:

Note Before you modify this key, we recommend that you back up this key. To do this, right-click CodeIdentifiers, and then click Export. Save the file to a location where you can find it on the computer.

 Change the PolicyScope registry value. To do this, double-click PolicyScope, and then change the setting from 0 to 1. Close Registry Editor. Click Start, click Run, type cmd, and then click OK to open a Command Prompt window. At the command prompt, type the following command, and then press ENTER:

net stop msiserver

This command stops the Windows Installer service if the service is currently running in the background. When the service has stopped, close the Command Prompt window, and then go to step 7.

Note If you receive the following message at the command prompt, close the Command Prompt window, and then go to step 7:

The Windows Installer service is not started

</li> Install the package that you were trying to install when you received the error message that is mentioned in the &quot;Symptoms&quot; section.</li> After you install the package, repeat steps 1 and 2. Then, change the PolicyScope registry value back to 0.</li> If you disconnected the computer from a domain, re-join the domain, and then restart the computer.

Note If you did not disconnect the computer from a domain, you do not have to restart the computer.</li></ol>

If the previous steps do not resolve the issue, follow these steps:
 * 1) Click Start, click Run, type control admintools, and then click OK.
 * 2) Double-click Local Security Policy.
 * 3) Click Software Restriction Policies.

Note If no software restrictions are listed, right-click Software Restriction Policies, and then click Create New Policy.
 * 1) Under Object Type, double-click Enforcement.
 * 2) Click All users except local administrators, and then click OK.
 * 3) Restart the computer.

Important After you follow the previous steps, local administrators can install the .msi package or the .msp package. After the package is installed, reset the enforcement level by following the previous steps. In step 5, click All users instead of All users except local administrators.

Notes
 * The workaround may not work in an Active Directory domain environment. In an Active Directory domain environment, a domain policy refresh operation will overwrite the local Software Restriction Policies.
 * Adding more RAM to the computer will not resolve the problem.

MORE INFORMATION
Starting with Microsoft Windows XP, a security policy named Software Restriction Policies (also known as SAFER) was introduced to help users avoid running unsafe files. Windows Installer uses Software Restriction Policies to verify the signatures of signed .msi package files and signed .msp package files. Windows Installer does this to make sure that the files were not tampered with before they are installed on the computer. Windows XP and Windows Server 2003 require the whole .msi package file or the whole .msp package file to be loaded into one contiguous piece of memory in the address space of the Windows Installer process.

If a .msi package file or a .msp package file is too large to fit into a contiguous piece of virtual memory, Windows Installer cannot verify that the package is correct. In this scenario, you experience the symptoms that are described in the “Symptoms” section. The fix that is described in this article enables Software Restriction Policies to use less virtual memory to perform the signature verification. Therefore, Windows Installer can verify any size files.
