ERROR
Note: This article pertains to ArcGIS versions 9.x only. Later versions of ArcGIS may contain different functionality, as well as different names and locations for menus, commands and geoprocessing tools. TheMSXML 4 Service Pack 2 is no longer available from the Microsoft download links listed below.
When launching ArcMap or ArcCatalog, the Windows MSI installer launches and tries to repair the ArcGIS Desktop installation. The following message displays:
"Please wait while Windows installer configures ArcGIS Desktop."
If the above message displays, open Event Viewer and perform the following steps:
"Detection of product '{1F34839E-4826-4B64-B1B3-42E5AE8DEC5A}', feature 'MicrosoftMsms', component '{303994BA-6487-47AE-AF1D-7AF6088EEBDB}' failed. The resource 'C:\WINDOWS\WinSxS\x86_Microsoft.MSXML2_6bd6b9abf345378f_4.20.9818.0_x-ww_8ff50c5d\msxml4.dll' does not exist."
A shared component that ArcGIS Desktop and Microsoft use is missing. MSXML4.dll is required by ArcGIS Desktop, and if the program cannot find this file, it begins to repair the installation.
NOTE If MSXML 4 Service Pack 2 is already installed, download again. Download ‘msxml.msi’ only. If this service pack was previously installed, an error message occurs during installation. This is expected; no action is required.
