When attempting to install updates using Windows update or Microsoft Update you may receive Error 0×643 or 0×80070643 when installing updates related to the .net framework.

Windows Installer uses the registry to record information about updates installed for each Windows Installer-based product. These registry keys help identify the state of each update: registered, applied, superseded, or obsoleted. Information about installed updates is stored across several registry keys and values. To allow for the product to be in a serviceable state in which it can be repaired, updated, or uninstalled, it is critical for the data in these registry keys to be synchronized. When the data in these registry keys is no longer synchronized, maintenance mode operations cannot be performed on the product .msi file.

The Patch Registration Cleanup Tool helps resolve some issues that are related to invalid or corrupted update registration. This tool lets you bring the product back to a known state so that you can reinstall updates.

On a computer that runs Windows Vista or Windows Server 2008, you uninstall some software updates. However, after the operation finishes, some of the software assembly files may reflect the updated version instead of the original version of the files.

For example, on a Windows Vista-based computer, assume that you have the 2007 Microsoft Office system installed. If you install and then uninstall 2007 Office system Service Pack 2 (SP2), some assembly files in the global assembly cache (%SystemRoot%\Assembly\GAC) remain from the 2007 Office system SP2 version.
