I encountered this error today after trying to reinstall SharePoint 2010 on my Windows 7 Enterprise 64 bit machine. It failed near the end of the binary installation. From the log file, I found that the “One or more required office components” failed during the setup was the installation of the SQL Server Express database for SharePoint. And the root cause of the problem was in the Windows Registry, which is HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\PendingFileRenameOperations.
