Beta Information
This article discusses a beta release of a Microsoft product. The information in this article is provided as-is and is subject to change without notice.

No formal product support is available from Microsoft for this beta product. For information about how to obtain support for a beta release, see the documentation that is included with the beta product files, or check the Web location where you downloaded the release.



SYMPTOMS
On a Windows Vista-based computer, or on a Windows Server code name &quot;Longhorn&quot;-based computer, you install an update package. However, the installation may fail. You may also receive the following error message:

Not enough storage is available to process this command.

Note The installation failure occurs if the update package is designed for one of the following operating systems:
 * Microsoft Windows 2000
 * Windows Server 2003
 * Windows XP

You find that there is sufficient free space on the hard disk and sufficient physical memory to install the package. Therefore, you may find that the error message is misleading.



CAUSE
The installation failure occurs because Update.exe tries to use a private and undocumented SetupAPI function. However, Windows Vista and Windows Server code name &quot;Longhorn&quot; do not support the SetupAPI function.

The Update.exe file of the update package calls the SetupAPI function to allocate a string table during the installation. However, because Windows Vista and Windows Server code name &quot;Longhorn&quot; do not support this function, the installation fails. The actual cause of the failure is that the Update.exe file does not allocate sufficient memory.



How the version of the Update.exe file influences the error message
If the version of the Update.exe file is earlier than 6.3.13.0, you receive the misleading error message that is mentioned in the &quot;Symptoms&quot; section when the installation fails. If the version of the Update.exe file is 6.3.13.0 or a later version, the error message indicates that the update package does not support the platform.

How to check the version of the Update.exe file
To check the version of the Update.exe file, follow these steps:  Type the following command at a command prompt to extract an update package to a temporary folder:

/X:

For example, to extract an update package that is named .exe to a folder that is named   on drive C, type the following command at a command prompt:

.exe /X:C:\

 In the temporary folder to which you extracted the update package in step 1, locate the Update.exe file. Right-click the Update.exe file, click Properties, and then click the Version tab. The file version appears on this tab.
