WORKAROUND

To work around this problem, use one of the following methods:

Method 1:Click OK to close the error message dialog boxes that are described in the "Symptoms" section. The Office XP SP3 installation will continue, and it will complete successfully.
Method 2:To prevent the error message, run a silent installation of Office XP SP3. To do this, click Start, click Run, type the following command, and then click OK:
Msiexec /p path\MAINSP3ff.MSP /qn /L*v C:\PatchLog.txt
Note This quiet mode command line will not succeed if either Windows Installer 3.1.4000.1823 or Windows Server 2003 SP1 has been installed on the computer.

To verify the version, check the file properties of the MSI.DLL file that is located in the C:\Windows\System32 folder. An update to the Windows Installer that will allow the command line to complete successfully is available from the following website:
