I have used the Customisation wizard to package a silent install of Adobe Reader X. We are upgrading from version 9. System Centre Configuration Manager reports a successful installation however on some computers this is not the case. On these computers there is an information type entry in the application log of Event Viewer. The source is MsiInstaller, Event ID: 11708 and a description of "Product: Adobe Reader X -- Installation operation failed.". Does anyone have any idea why this is being reported back to SCCM as successful? This also happens on some computers when deploying Acrobat X as well.
