It is a generic error code.

Typically, this means that an update was not installed. It is caused by a corruption in the .NET Framework installation or by an inconsistency on the MSI database state.

Please mention which update is exactly causing this error.

If it is a .NET corruption I noticed this link posted by A Guy earlier today. Download: .NET Framework Repair Tool - Microsoft Download Center - Download Details

And if it is a Silverlight update causing this, uninstalling Silverlight can be frustrating.

Try this: Backup your Registry, Search (Edit/Find) for silverlight.msi and you will find this key HKEY_CLASSES_ROOT\Installer\Products\D7314F9862C648A4DB8BE2A5B47BE100

Delete this key , and also delete all silverlight folders in programData and program files, restart. Download Silverlight Microsoft Silverlight and reinstall.

Hi there,

As pointed out by other members, your post isn't specific enough.

When does this occur? What does it refer to? Complete details of the error code?

You'll need to give us more information, before we can point you in the right direction.
