Method 1: Run the SR-1 Update Again

Even though you have already installed the SR-1 update, if you run it again, the Windows Installer will be updated to version 1.10.1029.1.

If you do not have the SR-1 update on your computer, click the following link to download the SR-1 update: After you download the update, double-click the file to update the Windows Installer.

NOTE: The SR-1 Update dialog boxes may indicate that the update was already applied. Ignore this text and continue with the update.

After you update the Windows Installer, run the SP-2 Update again.

NOTE: This problem with the SP-2 update only occurs if you use the update from the "Product Updates" page, not the Microsoft Download Center. However, the Windows Installer is still at the non SR-1 level if you apply the SP-2 update from the Download Center. Make sure to update the Windows Installer, if necessary, using Method 2 earlier in this article.

Follow these steps to verify the version of the Windows Installer that is on your computer:

1.	Locate Msi.dll on your computer. By default, this file is in the \Windows\System folder on Windows 95 and Windows 98 computers, or the \Winnt\System32 folder on Windows NT 4.0 computers.
2.	Right-click Msi.dll and then click Properties.
3.	Click the Version tab. Any version that is earlier than 1.10.1029.1 causes the problem described in the "Symptoms" section.
